Struct module_id::AccountAddress

pub struct AccountAddress(_);

A struct that represents an account address.

Implementations

impl AccountAddress

pub const fn new(address: [u8; 16]) -> AccountAddress

pub const LENGTH: usize

The number of bytes in an address. Default to 16 bytes, can be set to 20 bytes with address20 feature.

pub const ZERO: AccountAddress

Hex address: 0x0

pub const ONE: AccountAddress

Hex address: 0x1

pub fn random() -> AccountAddress

pub fn short_str_lossless(&self) -> String

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

pub fn into_bytes(self) -> [u8; 16]

pub fn from_hex_literal(
    literal: &str
) -> Result<AccountAddress, AccountAddressParseError>

pub fn to_hex_literal(&self) -> String

pub fn from_hex<T>(hex: T) -> Result<AccountAddress, AccountAddressParseError> where
    T: AsRef<[u8]>, 

pub fn to_hex(&self) -> String

pub fn from_bytes<T>(
    bytes: T
) -> Result<AccountAddress, AccountAddressParseError> where
    T: AsRef<[u8]>, 

Methods from Deref<Target = [u8; 16]>

pub fn as_slice(&self) -> &[T]

Returns a slice containing the entire array. Equivalent to &s[..].

pub fn each_ref(&self) -> [&T; N]

🔬 This is a nightly-only experimental API. (array_methods)

Borrows each element and returns an array of references with the same size as self.

Example

#![feature(array_methods)]

let floats = [3.1, 2.7, -1.0];
let float_refs: [&f64; 3] = floats.each_ref();
assert_eq!(float_refs, [&3.1, &2.7, &-1.0]);

This method is particularly useful if combined with other methods, like map. This way, you can avoid moving the original array if its elements are not Copy.

#![feature(array_methods)]

let strings = ["Ferris".to_string(), "♥".to_string(), "Rust".to_string()];
let is_ascii = strings.each_ref().map(|s| s.is_ascii());
assert_eq!(is_ascii, [true, false, true]);

// We can still access the original array: it has not been moved.
assert_eq!(strings.len(), 3);

pub fn split_array_ref<const M: usize>(&self) -> (&[T; M], &[T])

🔬 This is a nightly-only experimental API. (split_array)

Divides one array reference into two at an index.

The first will contain all indices from [0, M) (excluding the index M itself) and the second will contain all indices from [M, N) (excluding the index N itself).

Panics

Panics if M > N.

Examples

#![feature(split_array)]

let v = [1, 2, 3, 4, 5, 6];

{
   let (left, right) = v.split_array_ref::<0>();
   assert_eq!(left, &[]);
   assert_eq!(right, &[1, 2, 3, 4, 5, 6]);
}

{
    let (left, right) = v.split_array_ref::<2>();
    assert_eq!(left, &[1, 2]);
    assert_eq!(right, &[3, 4, 5, 6]);
}

{
    let (left, right) = v.split_array_ref::<6>();
    assert_eq!(left, &[1, 2, 3, 4, 5, 6]);
    assert_eq!(right, &[]);
}

pub fn rsplit_array_ref<const M: usize>(&self) -> (&[T], &[T; M])

🔬 This is a nightly-only experimental API. (split_array)

Divides one array reference into two at an index from the end.

The first will contain all indices from [0, N - M) (excluding the index N - M itself) and the second will contain all indices from [N - M, N) (excluding the index N itself).

Panics

Panics if M > N.

Examples

#![feature(split_array)]

let v = [1, 2, 3, 4, 5, 6];

{
   let (left, right) = v.rsplit_array_ref::<0>();
   assert_eq!(left, &[1, 2, 3, 4, 5, 6]);
   assert_eq!(right, &[]);
}

{
    let (left, right) = v.rsplit_array_ref::<2>();
    assert_eq!(left, &[1, 2, 3, 4]);
    assert_eq!(right, &[5, 6]);
}

{
    let (left, right) = v.rsplit_array_ref::<6>();
    assert_eq!(left, &[]);
    assert_eq!(right, &[1, 2, 3, 4, 5, 6]);
}
