impl WithdrawReasons

pub fn except(one: WithdrawReason) -> WithdrawReasons

Methods from Deref<Target = i8>

pub const MIN: i8

pub const MAX: i8

pub const BITS: u32

pub fn as_ne_bytes(&self) -> &[u8; 1]

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

Return the memory representation of this integer as a byte array in native byte order.

to_ne_bytes should be preferred over this whenever possible.

Examples

#![feature(num_as_ne_bytes)]
let num = 0x12i8;
let bytes = num.as_ne_bytes();
assert_eq!(
    bytes,
    if cfg!(target_endian = "big") {
        &[0x12]
    } else {
        &[0x12]
    }
