pub struct ByteField;
Expand description
A field encoder for u8.
This is separate from VarintField so that the packed format can be a byte array instead of a varint array.

source§const FIELD_TYPE: FieldType<'static> = _
const FIELD_TYPE: FieldType<'static> = _
The type of the field.

fn read_field( item: &mut InplaceOption<'_, u8>, reader: FieldReader<'_, '_, R>, ) -> Result<(), Error>
Reads a field into
item
.source§fn default_field(item: &mut InplaceOption<'_, u8>) -> Result<(), Error>
fn default_field(item: &mut InplaceOption<'_, u8>) -> Result<(), Error>
Instantiates
item
with its default value, if there is one. Read moresource§fn packed<'p, C>() -> Option<&'p dyn PackedDecode<'a, u8, C>>
fn packed<'p, C>() -> Option<&'p dyn PackedDecode<'a, u8, C>>
Unless
packed()::must_pack()
is true, the sequence decoder must detect
the encoding (packed or not) and call the appropriate method.source§fn wrap_in_sequence() -> bool
fn wrap_in_sequence() -> bool
Returns whether this field is wrapped in a message when encoded nested
in a sequence (such as a repeated field).
source§fn read_field_in_sequence(
item: &mut InplaceOption<'_, T>,
reader: FieldReader<'a, '_, R>,
) -> Result<(), Error>
fn read_field_in_sequence( item: &mut InplaceOption<'_, T>, reader: FieldReader<'a, '_, R>, ) -> Result<(), Error>
Reads this field that was encoded as part of a sequence, unwrapping it
from a message if necessary.
source§const ENTRY: DecoderEntry<'a, T, R> = _
const ENTRY: DecoderEntry<'a, T, R> = _
The table decoder entry for this type, used in types from
table::decode

fn packed<'a>() -> Option<&'a dyn PackedEncode<u8>>
Returns the encoder for writing multiple instances of this field in a
packed list, or
None
