Struct mesh_protobuf::encoding::ResourceField

pub struct ResourceField<T>(/* private fields */);

A field encoder for types that can be converted to and from OS resource type T.

Trait Implementations

impl<T> Default for ResourceField<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T, U, R> FieldDecode<'_, T, R> for ResourceField<U>

where T: From<U>, U: TryFrom<R>, U::Error: 'static + Error + Send + Sync,

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

Reads a field into item.

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

Instantiates item with its default value, if there is one.

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.

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).

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.

const ENTRY: DecoderEntry<'a, T, R> = _

The table decoder entry for this type, used in types from table::decode.

impl<T, U, R> FieldEncode<T, R> for ResourceField<U>

where T: Into<U>, U: Into<R>,

fn write_field(item: T, writer: FieldWriter<'_, '_, R>)

Writes item as a field.

fn compute_field_size(_item: &mut T, sizer: FieldSizer<'_>)

Computes the size of item as a field.

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

where T: 'a,

Returns the encoder for writing multiple instances of this field in a packed list, or None if there is no packed encoding for this type.

fn wrap_in_sequence() -> bool

Returns whether this field should be wrapped in a message when encoded nested in a sequence (such as a repeated field).

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.

fn compute_field_size_in_sequence(item: &mut T, sizer: &mut SequenceSizer<'_>)

Computes the size of this field as part of a sequence, including the size of a wrapping message.

const ENTRY: EncoderEntry<T, R> = _

The table encoder entry for this type, used in types from table::encode.
