Trait Implementations§

source§

impl<T, K, V, EK, EV> DescribeField<T> for MapField<K, V, EK, EV>

source§

const FIELD_TYPE: FieldType<'static> = _

The type of the field.
source§

const PACKED_TYPE: Option<&'static str> = None

The type name of the field in a packed context.
source§

impl<'a, K, V, T, EK, EV, R> FieldDecode<'a, T, R> for MapField<K, V, EK, EV>
where T: Default + Extend<(K, V)>, EK: FieldDecode<'a, K, R>, EV: FieldDecode<'a, V, R>,

source§

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

Reads a field into item.
source§

fn default_field(item: &mut InplaceOption<'_, T>) -> Result<(), Error>

Instantiates item with its default value, if there is one. Read more
source§

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 packed<'p, C>() -> Option<&'p dyn PackedDecode<'a, T, C>>
where C: CopyExtend<T>, 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 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§

The table decoder entry for this type, used in types from table::decode. Read more
source§

impl<K, V, T, EK, EV, R> FieldEncode<T, R> for MapField<K, V, EK, EV>

source§

fn packed<'a>() -> Option<&'a dyn PackedEncode<T>>
where T: 'a,

source§

fn write_field_in_sequence(item: T, writer: &mut SequenceWriter<'_, '_, R>)

Writes this field as part of a sequence, wrapping it in a message if necessary.
source§
