Struct VarUint 

pub struct VarUint(pub u32);

A variable-length unsigned integer.

Tuple Fields

0: u32

Implementations

impl VarUint

const MAX_SIZE: usize = 5

pub const fn written_size(self) -> usize

Returns the exact number of bytes this VarUInt will write when WriteTo::write is called, assuming no error occurs.

pub fn write(self, writer: &mut impl Write) -> Result<(), Error>

Writes a VarUint to a writer.

Errors

• If the writer fails to write.

pub fn read(read: &mut Cursor<&[u8]>) -> Result<u32, Error>

Reads a VarUint from a cursor.

Errors

• If the VarUint is too long.

Trait Implementations

impl Clone for VarUint

fn clone(&self) -> VarUint

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for VarUint

impl Debug for VarUint

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for VarUint

impl Hash for VarUint

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for VarUint

fn cmp(&self, other: &VarUint) -> 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 PartialEq for VarUint

fn eq(&self, other: &VarUint) -> 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 VarUint

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

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

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

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

fn le(&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.
