Expand description

An i32 encoded with variable length.

Tuple Fields§

§0: i32

Implementations§

Source§

impl VarInt

Source

pub const MAX_SIZE: usize = 5

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

Source

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.
