Struct soroban_sdk::Bytes

#[repr(transparent)]
pub struct Bytes(_);

Bytes is a contiguous growable array type containing u8s.

The array is stored in the Host and available to the Guest through the functions defined on Bytes.

Bytes values can be stored as ContractData, or in other types like Vec, Map, etc.

Examples

Bytes values can be created from slices:

use soroban_sdk::{Bytes, Env};

let env = Env::default();
let bytes = Bytes::from_slice(&env, &[1; 32]);
assert_eq!(bytes.len(), 32);
let mut slice = [0u8; 32];
bytes.copy_into_slice(&mut slice);
assert_eq!(slice, [1u8; 32]);
