Expand description

Builtin “function”-like operators that often have a signature not expressable in the type system and/or have access to some runtime/storage context

Variants§

§

Exists(StructName, Vec<Type>)

Check if there is a struct object (StructName resolved by current module) associated with the given address

§

BorrowGlobal(bool, StructName, Vec<Type>)

Get a reference to the resource(StructName resolved by current module) associated with the given address

§

MoveFrom(StructName, Vec<Type>)

Remove a resource of the given type from the account with the given address

§

MoveTo(StructName, Vec<Type>)

Publish an instantiated struct object into signer’s (signer is the first arg) account.

§

VecPack(Vec<Type>, u64)

Pack a vector fix a fixed number of elements. Zero elements means an empty vector.

§

VecLen(Vec<Type>)

Get the length of a vector

§

VecImmBorrow(Vec<Type>)

Acquire an immutable reference to the element at a given index of the vector

§

VecMutBorrow(Vec<Type>)

Acquire a mutable reference to the element at a given index of the vector

§

VecPushBack(Vec<Type>)

Push an element to the end of the vector

§

VecPopBack(Vec<Type>)

Pop and return an element from the end of the vector

§

VecUnpack(Vec<Type>, u64)

Destroy a vector of a fixed length. Zero length means destroying an empty vector.

§

VecSwap(Vec<Type>)

Swap the elements at twi indices in the vector

§

Freeze

Convert a mutable reference into an immutable one

§

ToU8

Cast an integer into u8.

§

ToU64

Cast an integer into u64.

§

ToU128

Cast an integer into u128.

impl PartialEq<Builtin> for Builtin

source§

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