Expand description

The type of an atom.

Variants§

§

Special

A value with a special meaning.

§

Int

A signed integer. Argument is the byte length, minus one. The following bytes are the value, stored in little endian.

§

UInt

An unsigned integer. Argument is the byte length, minus one. The following bytes are the value, stored in little endian.

§

Float

A floating point value. Argument is the byte length, minus one. Must be either 2, 4 or 8 bytes. The following bytes are the value, stored in little endian. The two-byte representation follows the IEEE 754-2008 standard, implemented by the half crate.

§

Sequence

A list of atoms. Argument is the count of atoms in the sequence.

§

Map

A list of key-value pairs. Argument is the count of entries in the map. There will be twice as many total atoms, since each entry is a key/value pair.

§

Symbol

A symbol. If the least-significant bit of the arg is 0, this is a new symbol. The remaining bits of the arg contain the length in bytes. The following bytes will contain the symbol bytes (UTF-8). It should be stored and given a unique symbol id, starting at 0.

If the least-significant bit of the arg is 1, the remaining bits are the symbol id of a previously emitted symbol.

§

Bytes

A series of bytes. The argument is the length. The bytes follow.

Implementations§

impl Kind

source

pub const fn from_u8(kind: u8) -> Result<Self, Error>

impl PartialEq<Kind> for Kind

source§

fn eq(&self, other: &Kind) -> bool
