Module pot::format

Low-level interface for reading and writing the pot format.

Structs

Atom

An encoded Kind, argument, and optional contained value.

Float

A floating point number that can safely convert between other number types using compile-time evaluation when possible.

Integer

An integer type that can safely convert between other number types using compile-time evaluation.

Enums

Kind

The type of an atom.

Nucleus

A value contained within an Atom.

Special

A special value type.

Functions

read_atom

Reads an atom.

read_atom_header

Reads an atom header (kind and argument).

read_header

Reads a Pot header. See write_header for more information. Returns the version number contained within.

write_atom_header

Writes an atom header into writer.

write_bool

Writes a Kind::Special atom with either Special::True or Special::False.

write_bytes

Writes an Kind::Bytes atom with the given value.

write_f32

Writes an Kind::Float atom with the given value.

write_f64

Writes an Kind::Float atom with the given value.

write_header

Writes the Pot header. A u32 written in big endian. The first three bytes are ‘Pot’ (0x506F74), and the fourth byte is the version. The first version of Pot is 0.

write_i8

Writes an Kind::Int atom with the given value. Will encode in a smaller format if possible.

write_i16

Writes an Kind::Int atom with the given value. Will encode in a smaller format if possible.

write_i24

Writes an Kind::Int atom with the given value. Will encode in a smaller format if possible.

write_i32

Writes an Kind::Int atom with the given value. Will encode in a smaller format if possible.

write_i48

Writes an Kind::Int atom with the given value. Will encode in a smaller format if possible.

write_i64

Writes an Kind::Int atom with the given value. Will encode in a smaller format if possible.

write_i128

Writes an Kind::Int atom with the given value. Will encode in a smaller format if possible.

write_named

Writes a Kind::Special atom with Special::Named.

write_none

Writes a Kind::Special atom with Special::None.

write_special

Writes a Kind::Special atom.

write_str

Writes an Kind::Bytes atom with the bytes of the string.

write_u8

Writes an Kind::UInt atom with the given value.

write_u16

Writes an Kind::Int atom with the given value. Will encode in a smaller format if possible.

write_u24

Writes an Kind::Int atom with the given value. Will encode in a smaller format if possible.

write_u32

Writes an Kind::Int atom with the given value. Will encode in a smaller format if possible.

write_u48

Writes an Kind::Int atom with the given value. Will encode in a smaller format if possible.

write_u64

Writes an Kind::Int atom with the given value. Will encode in a smaller format if possible.

write_u128

Writes an Kind::Int atom with the given value. Will encode in a smaller format if possible.

write_unit

Writes a Kind::Special atom with Special::Unit.
