Struct VariableBitSet 

pub struct VariableBitSet(pub Vec<i64>);

A dynamically-sized bit set encoded as a prefixed array of 64-bit words.

Minecraft’s protocol calls this type BitSet. Bits are addressed from the least-significant bit of the first word.

Tuple Fields

0: Vec<i64>

Implementations

impl VariableBitSet

pub const fn new() -> VariableBitSet

Creates an empty bit set.

pub fn bit(&self, idx: usize) -> bool

Returns whether the bit at idx is set.

pub fn set(&mut self, idx: usize)

Sets the bit at idx.

pub fn clear(&mut self, idx: usize)

Clears the bit at idx.

Clearing a bit past the current end is a no-op. Clearing the highest set bit shrinks the packed representation to match Java’s BitSet.

Trait Implementations

impl Clone for VariableBitSet

fn clone(&self) -> VariableBitSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VariableBitSet

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

Formats the value using the given formatter.

impl Decode<'_> for VariableBitSet

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

Reads this object from the provided byte slice.

impl Default for VariableBitSet

fn default() -> VariableBitSet

Returns the “default value” for a type.

impl Display for VariableBitSet

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

Formats the value using the given formatter.

impl Encode for VariableBitSet

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 PartialEq for VariableBitSet

fn eq(&self, other: &VariableBitSet) -> 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.
