Struct diem_crypto::validatable::Validatable

pub struct Validatable<V: Validate> { /* private fields */ }

Used in connection with the Validate trait to be able to represent types which can benefit from deferred validation as a performance optimization.

Implementations

impl<V: Validate> Validatable<V>

pub fn new_valid(valid: V) -> Self

Create a new Validatable from a valid type

pub fn new_unvalidated(unvalidated: V::Unvalidated) -> Self

Create a new Validatable from an unvalidated type

pub fn unvalidated(&self) -> &V::Unvalidated

Return a reference to the unvalidated form V::Unvalidated

pub fn valid(&self) -> Option<&V>

Try to validate the unvalidated form returning Some(&V) on success and None on failure.

pub fn validate(&self) -> Result<&V>

Attempt to validate V::Unvalidated and return a reference to a valid V

Trait Implementations

impl<V: Clone + Validate> Clone for Validatable<V>where V::Unvalidated: Clone,

fn clone(&self) -> Validatable<V>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<V: Debug + Validate> Debug for Validatable<V>where V::Unvalidated: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de, V> Deserialize<'de> for Validatable<V>where V: Validate, V::Unvalidated: Deserialize<'de>,

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<V> Hash for Validatable<V>where V: Validate, V::Unvalidated: Hash,

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<V> PartialEq<Validatable<V>> for Validatable<V>where V: Validate, V::Unvalidated: PartialEq,

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<V> Serialize for Validatable<V>where V: Validate + Serialize, V::Unvalidated: Serialize,

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>where S: Serializer,

Serialize this value into the given Serde serializer.

impl<V> Eq for Validatable<V>where V: Validate, V::Unvalidated: Eq,
