Icon LinkAssetId

Like Bytes32, AssetId is a wrapper on [u8; 32] with similar methods and implements the same traits (see fuel-types documentation Icon Link).

These are the main ways of creating an AssetId:

use std::str::FromStr;
 
use fuels::types::AssetId;
 
// Zeroed Bytes32
let asset_id = AssetId::zeroed();
 
// Grab the inner `[u8; 32]` from
// `Bytes32` by dereferencing (i.e. `*`) it.
assert_eq!([0u8; 32], *asset_id);
 
// From a `[u8; 32]`.
let my_slice = [1u8; 32];
let asset_id = AssetId::new(my_slice);
assert_eq!([1u8; 32], *asset_id);
 
// From a string.
let hex_str = "0x0000000000000000000000000000000000000000000000000000000000000000";
let asset_id = AssetId::from_str(hex_str)?;
assert_eq!([0u8; 32], *asset_id);
