Struct LeU64 

pub struct LeU64(/* private fields */);

64-bit unsigned little-endian integer. Alignment 1.

The workhorse type for token amounts, lamport balances, timestamps, and most on-chain numeric fields. Use this instead of u64 in any #[repr(C)] struct that will be projected from account data.

Implementations

impl LeU64

pub const ZERO: Self

Zero value.

pub const MAX: Self

Maximum representable value.

pub const fn new(v: u64) -> Self

Construct from a native integer (const-safe).

pub const fn get(self) -> u64

Read the native integer value.

pub const fn to_le_bytes(self) -> [u8; 8]

Raw little-endian bytes.

pub const fn from_le_bytes(bytes: [u8; 8]) -> Self

pub const fn checked_add(self, rhs: Self) -> Option<Self>

Checked addition. Returns None on overflow.

Checked subtraction. Returns None on underflow.

pub const fn checked_mul(self, rhs: Self) -> Option<Self>

Checked multiplication. Returns None on overflow.

pub const fn checked_div(self, rhs: Self) -> Option<Self>

Checked division. Returns None on divide-by-zero.
