Struct musli_wire::tag::Tag

source · [−]

#[repr(transparent)]
pub struct Tag { /* private fields */ }

Expand description

A type tag.

The Kind of the element is indicates by its 2 MSBs, and remaining 6 bits is the data field. The exact use of the data field depends on the Kind in question. It is primarily used to smuggle extra data for the kind in question.

Implementations

source

impl Tag

source

pub const fn new(kind: Kind, data: u8) -> Self

Construct a new tag through an unchecked constructor.

data must not be equal to or larger than [DATA_MASK], or else it could corrupt the payload.

source

pub const fn empty(kind: Kind) -> Self

Construct a new empty tag of the given Kind.

source

pub const fn from_byte(repr: u8) -> Self

Construct from a byte.

source

pub const fn byte(self) -> u8

Coerce type flag into a byte.

source

pub const fn kind(self) -> Kind

Access the kind of the tag.

source

pub const fn data(self) -> Option<u8>

Perform checked access over the internal data. Returns None if data is empty.

source

pub const fn with_len(kind: Kind, len: usize) -> (Self, bool )

Attempt to construct a type tag with the given length embedded.

Returns a tuple where the boolean indicates if the value was embedded or not.

source

pub const fn with_byte(kind: Kind, len: u8) -> (Self, bool )

Attempt to construct a type tag with the given length embedded.

Returns a tuple where the boolean indicates if the value was embedded or not.
