Struct multiversx_sc::types::heap::Address

pub struct Address(_);

An Address is just a H256 with a different name. Has a different ABI name than H256.

Note: we are currently using ManagedAddress in contracts. While this also works, its use in contracts is discouraged.

Implementations

impl Address

pub fn from_slice(slice: &[u8]) -> Self

impl Address

pub fn zero() -> Self

Returns a new address of 32 zeros. Allocates directly in heap. Minimal resulting wasm code (14 bytes if not inlined).

pub fn len_bytes() -> usize

Returns the size of an address in bytes.

pub fn as_bytes(&self) -> &[u8]

Extracts a byte slice containing the entire fixed hash.

pub fn as_array(&self) -> &[u8; 32]

pub fn copy_to_array(&self, target: &mut [u8; 32])

pub fn to_vec(&self) -> Vec<u8>

pub fn as_ptr(&self) -> *const u8

Pointer to the data on the heap.

pub fn as_mut_ptr(&mut self) -> *mut u8

Returns an unsafe mutable pointer to the data on the heap. Used by the API to populate data.

pub fn is_zero(&self) -> bool

True if all 32 bytes of the hash are zero.

pub fn into_boxed_bytes(self) -> BoxedBytes

Transmutes self to an (in principle) variable length boxed bytes object. Both BoxedBytes and H256 keep the data on the heap, so only the pointer to that data needs to be transmuted. Does not reallocate or copy data, the data on the heap remains untouched.

Trait Implementations

fn from(bytes: &'a mut [u8; 32]) -> Self

Converts to this type from the input type.

impl<M> From<&Address> for ManagedAddress<M>where M: ManagedTypeApi,

fn from(address: &Address) -> Self

Converts to this type from the input type.

impl From<[u8; 32]> for Address

fn from(arr: [u8; 32]) -> Self

Converts to this type from the input type.

impl From<Address> for [u8; 32]

fn from(addr: Address) -> Self

Converts to this type from the input type.

impl From<Address> for H256

fn from(address: Address) -> Self

Converts to this type from the input type.

impl<M> From<Address> for ManagedAddress<M>where M: ManagedTypeApi,

fn from(address: Address) -> Self

Converts to this type from the input type.

impl From<Box<[u8; 32], Global>> for Address

fn from(bytes: Box<[u8; 32]>) -> Self

Converts to this type from the input type.

impl From<H256> for Address

fn from(hash: H256) -> Self

Converts to this type from the input type.

impl Hash for Address

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 NestedDecode for Address

fn dep_decode_or_handle_err<I, H>( input: &mut I, h: H ) -> Result<Self, H::HandledErr>where I: NestedDecodeInput, H: DecodeErrorHandler,

Version of dep_decode that can handle errors as soon as they occur. For instance in can exit immediately and make sure that if it returns, it is a success. By not deferring error handling, this can lead to somewhat smaller bytecode.

fn dep_decode<I>(input: &mut I) -> Result<Self, DecodeError>where I: NestedDecodeInput,

Attempt to deserialise the value from input, using the format of an object nested inside another structure. In case of success returns the deserialized value and the number of bytes consumed during the operation.

impl NestedEncode for Address

fn dep_encode_or_handle_err<O, H>( &self, dest: &mut O, h: H ) -> Result<(), H::HandledErr>where O: NestedEncodeOutput, H: EncodeErrorHandler,

Version of dep_encode that can handle errors as soon as they occur. For instance in can exit immediately and make sure that if it returns, it is a success. By not deferring error handling, this can lead to somewhat smaller bytecode.

fn dep_encode<O>(&self, dest: &mut O) -> Result<(), EncodeError>where O: NestedEncodeOutput,

NestedEncode to output, using the format of an object nested inside another structure. Does not provide compact version.

impl PartialEq<Address> for Address

fn eq(&self, other: &Address) -> 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 TopDecode for Address

fn top_decode_or_handle_err<I, H>(input: I, h: H) -> Result<Self, H::HandledErr>where I: TopDecodeInput, H: DecodeErrorHandler,

Version of top_decode that can handle errors as soon as they occur. For instance it can exit immediately and make sure that if it returns, it is a success. By not deferring error handling, this can lead to somewhat smaller bytecode.

fn top_decode<I>(input: I) -> Result<Self, DecodeError>where I: TopDecodeInput,

Attempt to deserialize the value from input.

impl TopEncode for Address

fn top_encode_or_handle_err<O, H>( &self, output: O, h: H ) -> Result<(), H::HandledErr>where O: TopEncodeOutput, H: EncodeErrorHandler,

Version of top_encode that can handle errors as soon as they occur. For instance in can exit immediately and make sure that if it returns, it is a success. By not deferring error handling, this can lead to somewhat smaller bytecode.

fn top_encode<O>(&self, output: O) -> Result<(), EncodeError>where O: TopEncodeOutput,

Attempt to serialize the value to ouput.

impl TypeAbi for Address

fn type_name() -> TypeName

fn provide_type_descriptions<TDC: TypeDescriptionContainer>( accumulator: &mut TDC )

A type can provide more than its own description. For instance, a struct can also provide the descriptions of the type of its fields. TypeAbi doesn’t care for the exact accumulator type, which is abstracted by the TypeDescriptionContainer trait.
