Required Methods

Implementations on Foreign Types

impl EncodedSize for bool

A boolean always occupies exactly one byte on the wire.

fn encoded_size(&self) -> usize

impl EncodedSize for f32

The encoded size is always 4 bytes, regardless of the value.

fn encoded_size(&self) -> usize

impl EncodedSize for f64

The encoded size is always 8 bytes, regardless of the value.

fn encoded_size(&self) -> usize

impl EncodedSize for i8

The encoded size is always 1 bytes, regardless of the value.

fn encoded_size(&self) -> usize

impl EncodedSize for i16

The encoded size is always 2 bytes, regardless of the value.

fn encoded_size(&self) -> usize

impl EncodedSize for i32

The encoded size is always 4 bytes, regardless of the value.

fn encoded_size(&self) -> usize

impl EncodedSize for i64

The encoded size is always 8 bytes, regardless of the value.

fn encoded_size(&self) -> usize

impl EncodedSize for u8

The encoded size is always 1 bytes, regardless of the value.

fn encoded_size(&self) -> usize

impl EncodedSize for u16

The encoded size is always 2 bytes, regardless of the value.

fn encoded_size(&self) -> usize

impl EncodedSize for u32

The encoded size is always 4 bytes, regardless of the value.

fn encoded_size(&self) -> usize

impl EncodedSize for u64

The encoded size is always 8 bytes, regardless of the value.

fn encoded_size(&self) -> usize

impl EncodedSize for String

Computes the wire size of a Minecraft protocol string.

The total size is the VarInt-encoded length prefix plus the UTF-8 byte count. This enables exact buffer pre-allocation before encoding.

fn encoded_size(&self) -> usize

Returns the VarInt prefix size plus the string’s byte length.

impl EncodedSize for Vec<u8>

Computes the wire size of a Minecraft protocol byte array.

The total size is the VarInt-encoded length prefix plus the byte count. This enables exact buffer pre-allocation before encoding.

fn encoded_size(&self) -> usize

Returns the VarInt prefix size plus the array’s byte length.

impl<T: EncodedSize + ?Sized> EncodedSize for Box<T>

fn encoded_size(&self) -> usize

Implementors

impl EncodedSize for NbtTag

Computes the wire size of an NbtTag as a network NBT root.

impl EncodedSize for NbtCompound

Computes the wire size of a network NBT root compound.

Includes the compound type byte (1) plus the compound payload size (entries + End tag).

impl EncodedSize for Angle

An Angle always occupies exactly 1 byte on the wire.

impl EncodedSize for BitSet

Computes the wire size of the BitSet.

The total size is the VarInt-encoded length prefix plus 8 bytes per long. This enables exact buffer pre-allocation before encoding.

impl EncodedSize for Identifier

Computes the wire size of the identifier in namespace:path format.

The total size includes the VarInt length prefix and the full namespace:path UTF-8 byte count (including the colon separator).

impl EncodedSize for OpaqueBytes

impl EncodedSize for Position

A Position always occupies exactly 8 bytes on the wire (one packed i64).

impl EncodedSize for Slot

Computes the wire size of a Slot.

impl EncodedSize for TextComponent

Computes the wire size of a TextComponent as network NBT.

Converts to NbtCompound and delegates to its EncodedSize. This involves building the full NBT tree, so it is not free — use sparingly or cache the result when encoding multiple times.

impl EncodedSize for Uuid

A UUID always occupies exactly 16 bytes on the wire.

impl EncodedSize for VarInt

Computes the number of bytes this VarInt will occupy when encoded.

Returns 1-5 based on the unsigned magnitude of the value. Small positive values (0-127) take 1 byte, while negative values always take 5 bytes due to two’s complement sign extension.

impl EncodedSize for VarLong

Computes the number of bytes this VarLong will occupy when encoded.

Returns 1-10 based on the unsigned magnitude. Small positive values (0-127) take 1 byte, i64::MAX takes 9, and negative values always take 10 bytes.

impl EncodedSize for Vec2f

A Vec2f always occupies 8 bytes (2 × f32).

impl EncodedSize for Vec3f64

A Vec3f64 always occupies 24 bytes (3 × f64).

impl EncodedSize for Vec3f

A Vec3f always occupies 12 bytes (3 × f32).

impl EncodedSize for Vec3i16

A Vec3i16 always occupies 6 bytes (3 × i16).
