Implementations§

source§

impl VarUint248

source

pub const ONE: Self = _

The multiplicative identity for this integer type, i.e. 1.

source

pub const MIN: Self = _

The smallest value that can be represented by this integer type.

source

pub const MAX: Self = _

The largest value that can be represented by this integer type.

source

pub const LEN_BITS: u16 = 5u16

The number of data bits that the length occupies.

source

pub const MAX_BITS: u16 = 253u16

The maximum number of data bits that this struct occupies.

source

pub const fn new(value: u128) -> Self

Creates a new integer value from a primitive integer.

source

pub const fn from_words(hi: u128, lo: u128) -> Self

Constructs self from a pair of high and low underlying integers.

source

pub const fn into_words(self) -> (u128, u128)

Returns a tuple of high and low underlying integers.

source

pub const fn is_zero(&self) -> bool

Returns true if an underlying primitive integer is zero.

source

pub const fn is_valid(&self) -> bool

Returns true if an underlying primitive integer fits into the repr.

source

pub const fn bit_len(&self) -> Option<u16>

Returns number of data bits that this struct occupies. Returns None if an underlying primitive integer is too large.

source

pub const fn leading_zeros(&self) -> u32
