Struct mesh_protobuf::oneof::OneofEncoder
source · pub struct OneofEncoder;
Expand description
An encoder type for oneof
fields derived from Rust enums.
Encoding and decoding are implemented on types that implement
OneofEncode
and OneofDecode
.

fn read_field( item: &mut InplaceOption<'_, T>, reader: FieldReader<'de, '_, R>, ) -> Result<()>
Reads a field into
item
.source§fn default_field(_item: &mut InplaceOption<'_, T>) -> Result<()>
fn default_field(_item: &mut InplaceOption<'_, T>) -> Result<()>
Instantiates
item
with its default value, if there is one. Read moresource§fn packed<'p, C: CopyExtend<T>>() -> Option<&'p dyn PackedDecode<'a, T, C>>where
T: 'p,

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<()>
fn read_field_in_sequence( item: &mut InplaceOption<'_, T>, reader: FieldReader<'a, '_, R>, ) -> Result<()>
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> = _
