Tuple Fields

0: i64

Implementations

impl VarLong

pub const MAX_SIZE: usize = 10

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

pub fn written_size(self) -> usize

Returns the exact number of bytes this varlong 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 VarLongs 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.

Trait Implementations

impl Clone for VarLong

fn clone(&self) -> VarLong

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VarLong

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

Formats the value using the given formatter.

impl Decode<'_> for VarLong

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

Reads this object from the provided byte slice.

impl Default for VarLong

fn default() -> VarLong

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for VarLong

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for VarLong

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<VarLong> for i64

fn from(value: VarLong) -> i64

Converts to this type from the input type.

impl From<i64> for VarLong

fn from(value: i64) -> VarLong

Converts to this type from the input type.

impl Hash for VarLong

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 VarLong

fn cmp(&self, other: &VarLong) -> 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 VarLong

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

fn partial_cmp(&self, other: &VarLong) -> 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 VarLong

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.
