Struct VarInt 

pub struct VarInt(pub i32);

A variable-length integer.

Tuple Fields

0: i32

Implementations

impl VarInt

pub const MAX_SIZE: usize = 5

The maximum number of bytes a VarInt can be.

pub const fn written_size(val: i32) -> usize

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

pub async fn read_async( read: &mut (impl AsyncRead + Unpin), ) -> Result<i32, Error>

Reads a VarInt from an async reader.

Errors

• If the VarInt is too long.

pub async fn write_async( self, write: &mut (impl AsyncWrite + Unpin), ) -> Result<(), Error>

Writes a VarInt to an async writer.

Errors

• If the writer fails to write.

pub fn set_in_front(self, vec: &mut FrontVec, varint_size: usize)

Sets the VarInt in front of a FrontVec.

Panics

• If the VarInt fails to write to the buffer.

Trait Implementations

Performs copy-assignment from source.

impl Copy for VarInt

impl Debug for VarInt

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

Formats the value using the given formatter.

impl Eq for VarInt

impl From<VarInt> for usize

fn from(value: VarInt) -> usize

Converts to this type from the input type.

impl From<VarInt> for i32

fn from(value: VarInt) -> i32

Converts to this type from the input type.

impl From<i32> for VarInt

fn from(value: i32) -> Self

Converts to this type from the input type.

impl From<usize> for VarInt

fn from(value: usize) -> Self

Converts to this type from the input type.

impl Hash for VarInt

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 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 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 (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.

impl ReadFrom for VarInt

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

Reads data from a cursor.

impl StructuralPartialEq for VarInt

impl WriteTo for VarInt

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

Writes data to a writer.
