Struct Tag

pub struct Tag {
    pub field_number: FieldNumber,
    pub wire_type: WireType,
}

A protobuf tag has two parts: A field_number and a wire_type.

Fields

field_number: FieldNumber

The field number of this tag.

wire_type: WireType

The wire type of this tag.

Trait Implementations

impl Clone for Tag

fn clone(&self) -> Tag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Tag

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

Formats the value using the given formatter.

impl Packable for Tag

fn pack_sz(&self) -> usize

pack_sz returns the number of bytes required to serialize the Packable object.

fn pack(&self, buf: &mut [u8])

pack fills in the buffer out with the packed binary representation of the Packable object. The implementor is responsible to ensure that out is exactly pack_sz() bytes and implementations are encouraged to assert this.

fn stream<W>(&self, writer: &mut W) -> Result<usize, Error>

where W: Write, Self: Sized, &'a Self: for<'a> Packable,

stream writes the object to the provided writer using the same representation that would be used in a call to pack. The implementor is responsible for making sure that the number of bytes written is exactly equal to the number of required bytes.

impl PartialEq for Tag

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl<'a> Unpackable<'a> for Tag

type Error = Error

Type of error this unpackable returns.

fn unpack<'b: 'a>(buf: &'b [u8]) -> Result<(Self, &'b [u8]), Error>

unpack attempts to return an Unpackable object stored in a prefix of buf. The method returns the result and remaining unused buffer.
