fn read_field( item: &mut InplaceOption<'_, Vec<T>>, reader: FieldReader<'a, '_, R>, ) -> Result<(), Error>
Reads a field into
item
.source§fn default_field(item: &mut InplaceOption<'_, Vec<T>>) -> Result<(), Error>
fn default_field(item: &mut InplaceOption<'_, Vec<T>>) -> Result<(), Error>
Instantiates
item
with its default value, if there is one. Read moresource§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).

Unless
packed()::must_pack()
is true, the sequence decoder must detect
the encoding (packed or not) and call the appropriate method.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.
