Implementations

impl VarInt

pub const fn new(u: u64) -> VarInt

pub fn with(u: impl Into<usize>) -> VarInt

pub const fn len(&self) -> usize

Gets the length of this VarInt when encoded.

Returns 1 for 0..=0xFC, 3 for 0xFD..=(2^16-1), 5 for 0x10000..=(2^32-1), and 9 otherwise.

pub const fn to_u64(&self) -> u64

pub const fn into_u64(self) -> u64

pub fn to_usize(&self) -> usize

pub fn into_usize(self) -> usize

impl Ord for VarInt

fn cmp(&self, other: &VarInt) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<U> PartialEq<U> for VarInt

where U: Into<u64> + Copy,

fn eq(&self, other: &U) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq for VarInt

fn eq(&self, other: &VarInt) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for VarInt

fn partial_cmp(&self, other: &VarInt) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
