Struct read_write_set::dynamic_analysis::ConcretizedFormals

pub struct ConcretizedFormals(_);

A read/write set state with no unbound formals or type variables

Implementations

impl ConcretizedFormals

pub fn get_keys_(&self, is_write: bool, env: &GlobalEnv) -> Vec<ResourceKey>

Return the ResourceKey’s that may be accessed by self. If is_write is true, return the keys that may be written; otherwise, return the keys that may be read. For example: if self is 0x7/0x1::AModule::AResource/f/g -> ReadWrite, this will return 0x7/0x1::AModule.

pub fn get_keys_written(&self, env: &GlobalEnv) -> Vec<ResourceKey>

Return the ResourceKey’s written by self.

pub fn get_keys_read(&self, env: &GlobalEnv) -> Vec<ResourceKey>

Return the ResourceKey’s read by self.

pub fn from_args( accesses: AccessPathTrie<Access>, signers: &[AccountAddress], actuals: &[Vec<u8>], type_actuals: &[TypeTag], fun_env: &FunctionEnv<'_> ) -> Result<ConcretizedFormals>

Construct a ConcretizedFormals from accesses by binding the formals and type variables in accesses to signers/actuals and type_actuals. For example: if accesses is Formal(0)/0x1::M::S<TypeVar(0)>/f -> Read, signers is 0xA and type_actuals is 0x2::M2::S2, this will return 0xA/0x1::M::S<0x2::M2::S@>/f -> Read

pub fn get_child_data(&self) -> Option<T>

pub fn get_local( &self, local_index: usize, fun_env: &FunctionEnv<'_> ) -> Option<&T>

Retrieve the data associated with local_index in the trie. Returns None if there is no associated data

pub fn get_local_node( &self, local_index: usize, fun_env: &FunctionEnv<'_> ) -> Option<&TrieNode<T>>

Retrieve the node associated with local_index in the trie. Returns None if there is no associated node

pub fn local_exists(&self, local_index: usize, fun_env: &FunctionEnv<'_>) -> bool

Return true if there is a value bound to local variable local_index

pub fn keys_statically_known(&self) -> bool

Return true if the keys of self have no dynamic components and thus can be converted into a compact set of concrete access paths.

Apply f to each offset in self

pub fn iter_paths_opt<F>(&self, f: F)where F: FnMut(&AccessPath, &Option<&T>),

Apply f to each (access path, Option(data)) pair encoded in self

pub fn iter_paths<F>(&self, f: F)where F: FnMut(&AccessPath, &T),

Methods from Deref<Target = MapDomain<Root, TrieNode<T>>>

pub fn insert_join(&mut self, k: K, v: V) -> JoinResult

Join v with self[k] if k is bound, insert v otherwise

pub fn update_values(&mut self, f: impl FnMut(&mut V))

Updates the values in the range of the map using the given function. Notice that with other kind of map representations we would use iter_mut for this, but this is not available in OrdMap for obvious reasons (because entries are shared), so we need to use this pattern here instead.

Methods from Deref<Target = OrdMap<K, V>>

pub fn is_empty(&self) -> bool

Test whether a map is empty.

Time: O(1)

Examples

assert!(
  !ordmap!{1 => 2}.is_empty()
);
assert!(
  OrdMap::<i32, i32>::new().is_empty()
);

pub fn ptr_eq(&self, other: &OrdMap<K, V>) -> bool

Test whether two maps refer to the same content in memory.

This is true if the two sides are references to the same map, or if the two maps refer to the same root node.

This would return true if you’re comparing a map to itself, or if you’re comparing a map to a fresh clone of itself.

Time: O(1)

pub fn len(&self) -> usize

Get the size of a map.

Time: O(1)

Examples

assert_eq!(3, ordmap!{
  1 => 11,
  2 => 22,
  3 => 33
}.len());

pub fn clear(&mut self)

Discard all elements from the map.

This leaves you with an empty map, and all elements that were previously inside it are dropped.

Time: O(n)

Examples

let mut map = ordmap![1=>1, 2=>2, 3=>3];
map.clear();
assert!(map.is_empty());

pub fn get_max(&self) -> Option<&(K, V)>

Get the largest key in a map, along with its value. If the map is empty, return None.

Time: O(log n)

Examples

assert_eq!(Some(&(3, 33)), ordmap!{
  1 => 11,
  2 => 22,
  3 => 33
}.get_max());

pub fn get_min(&self) -> Option<&(K, V)>

Get the smallest key in a map, along with its value. If the map is empty, return None.

Time: O(log n)

Examples

assert_eq!(Some(&(1, 11)), ordmap!{
  1 => 11,
  2 => 22,
  3 => 33
}.get_min());

pub fn iter(&self) -> Iter<'_, K, V>

Get an iterator over the key/value pairs of a map.

pub fn range<R, BK>(&self, range: R) -> Iter<'_, K, V>where R: RangeBounds<BK>, K: Borrow<BK>, BK: Ord + ?Sized,

Create an iterator over a range of key/value pairs.

pub fn keys(&self) -> Keys<'_, K, V>

Get an iterator over a map’s keys.

pub fn values(&self) -> Values<'_, K, V>

Get an iterator over a map’s values.

pub fn diff<'a>(&'a self, other: &'a OrdMap<K, V>) -> DiffIter<'a, K, V>

Get an iterator over the differences between this map and another, i.e. the set of entries to add, update, or remove to this map in order to make it equal to the other map.

This function will avoid visiting nodes which are shared between the two maps, meaning that even very large maps can be compared quickly if most of their structure is shared.

Time: O(n) (where n is the number of unique elements across the two maps, minus the number of elements belonging to nodes shared between them)

pub fn get<BK>(&self, key: &BK) -> Option<&V>where BK: Ord + ?Sized, K: Borrow<BK>,

assert_eq!(
  map.get(&123),
  Some(&"lol")
);

pub fn get_key_value<BK>(&self, key: &BK) -> Option<(&K, &V)>where BK: Ord + ?Sized, K: Borrow<BK>,

Time: O(log n)

Examples

let map = ordmap!{123 => "lol"};
assert_eq!(

);

pub fn get_prev<BK>(&self, key: &BK) -> Option<(&K, &V)>where BK: Ord + ?Sized, K: Borrow<BK>,

Examples

let map = ordmap![1 => 1, 3 => 3, 5 => 5];
assert_eq!(Some((&3, &3)), map.get_prev(&4));

pub fn get_next<BK>(&self, key: &BK) -> Option<(&K, &V)>where BK: Ord + ?Sized, K: Borrow<BK>,

Get the closest larger entry in a map to a given key as a mutable reference.

If the set contains the given value, this is returned. Otherwise, the closest value in the set larger than the given value is returned. If the largest value in the set is smaller than the given value, None is returned.

Examples

let map = ordmap![1 => 1, 3 => 3, 5 => 5];

pub fn get_mut<BK>(&mut self, key: &BK) -> Option<&mut V>where BK: Ord + ?Sized, K: Borrow<BK>,

Get a mutable reference to the value for a key from a map.

Time: O(log n)

}
assert_eq!(ordmap![1 => 1, 3 => 3, 5 => 4], map);

pub fn insert(&mut self, key: K, value: V) -> Option<V>

Insert a key/value mapping into a map.

This is a copy-on-write operation, so that the parts of the map’s structure which are shared with other maps will be safely copied before mutating.

If the map already has a mapping for the given key, the previous value is overwritten.

Time: O(log n)

Examples

let mut map = ordmap!{};
map.insert(123, "123");
map.insert(456, "456");
assert_eq!(
  map,

  ordmap!{123 => "123"}

pub fn alter<F>(&self, f: F, k: K) -> OrdMap<K, V>where F: FnOnce(Option<V>) -> Option<V>,

Update the value for a given key by calling a function with the current value and overwriting it with the function’s return value.

The function gets an Option<V> and returns the same, so that it can decide to delete a mapping instead of updating the value, and decide what to do if the key isn’t in the map.

Time: O(log n)
