Enum bonsaidb::core::transmog_pot::pot::format::Kind

pub enum Kind {
    Special,
    Int,
    UInt,
    Float,
    Sequence,
    Map,
    Symbol,
    Bytes,
}

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 4 or 8 bytes. The following bytes are the value, stored in little endian.

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

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

Converts from a u8. Returns an error if kind is an invalid value.

Trait Implementations

impl Clone for Kind

fn clone(&self) -> Kind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Kind

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

Formats the value using the given formatter.

impl PartialEq<Kind> for Kind

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
