Struct VarInt 

#[repr(transparent)]
pub struct VarInt(pub i32);

An i32 encoded with variable length.

Tuple Fields

0: i32

Implementations

impl VarInt

pub const MAX_SIZE: usize = 5

The maximum number of bytes a VarInt could occupy when read from and written to the Minecraft protocol.

pub const fn written_size(self) -> usize

Returns the exact number of bytes this varint will write when [Encode::encode] is called, assuming no error occurs.

This is the size of “canonical” (non-padded) encoding for this value, not necessarily the number of bytes that were consumed while decoding it. Minecraft VarInts may be padded by using more continuation bytes than the value requires, so callers that need the decoded wire length should compare the input slice length before and after decoding instead.

pub fn decode_partial<R>(r: R) -> Result<i32, VarIntDecodeError>

Trait Implementations

impl Clone for VarInt

fn clone(&self) -> VarInt

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VarInt

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

Formats the value using the given formatter.

impl Decode<'_> for VarInt

fn decode(r: &mut &[u8]) -> Result<VarInt, Error>

Reads this object from the provided byte slice.

impl Default for VarInt

fn default() -> VarInt

Returns the “default value” for a type.

impl Deref for VarInt

type Target = i32

The resulting type after dereferencing.

fn deref(&self) -> &<VarInt as Deref>::Target

Dereferences the value.

impl DerefMut for VarInt

fn deref_mut(&mut self) -> &mut <VarInt as Deref>::Target

Mutably dereferences the value.

impl<'de> Deserialize<'de> for VarInt

fn deserialize<__D>( __deserializer: __D, ) -> Result<VarInt, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for VarInt

fn encode(&self, w: impl Write) -> Result<(), Error>

Writes this object to the provided writer.

fn encode_slice(slice: &[Self], w: impl Write) -> Result<(), Error>

where Self: Sized,

Like [Encode::encode], except that a whole slice of values is encoded.

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) -> VarInt

Converts to this type from the input type.

impl Hash for VarInt

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

where __H: Hasher,

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 Serialize for VarInt

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
