Struct TransparentEncoding

pub struct TransparentEncoding<E>(/* private fields */);

An encoding derived by mesh_derive for a transparent type, using inner encoding E.

Trait Implementations

impl<E> Clone for TransparentEncoding<E>

where E: Clone,

fn clone(&self) -> TransparentEncoding<E>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T, E> DescribeField<T> for TransparentEncoding<E>

where T: Transparent, E: DescribeField<<T as Transparent>::Inner>,

const FIELD_TYPE: FieldType<'static> = E::FIELD_TYPE

The type of the field.

const PACKED_TYPE: Option<&'static str> = E::PACKED_TYPE

The type name of the field in a packed context.

impl<T, E> DescribeMessage<T> for TransparentEncoding<E>

where T: Transparent, E: DescribeMessage<<T as Transparent>::Inner>,

const DESCRIPTION: MessageDescription<'static> = E::DESCRIPTION

The message description.

impl<'de, T, E, R> FieldDecode<'de, T, R> for TransparentEncoding<E>

where T: Transparent, E: FieldDecode<'de, <T as Transparent>::Inner, R>,

const ENTRY: DecoderEntry<'de, T, R>

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

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

Reads a field into item.

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

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

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 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.

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.

impl<T, E, R> FieldEncode<T, R> for TransparentEncoding<E>

where T: Transparent, E: FieldEncode<<T as Transparent>::Inner, R>,

const ENTRY: EncoderEntry<T, R>

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

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 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 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 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.

impl<'de, T, E, R> MessageDecode<'de, T, R> for TransparentEncoding<E>

where T: Transparent, E: MessageDecode<'de, <T as Transparent>::Inner, R>,

fn read_message( item: &mut InplaceOption<'_, T>, reader: MessageReader<'de, '_, R>, ) -> Result<(), Error>

Reads a message into item.

impl<T, E, R> MessageEncode<T, R> for TransparentEncoding<E>

where T: Transparent, E: MessageEncode<<T as Transparent>::Inner, R>,

fn write_message(item: T, writer: MessageWriter<'_, '_, R>)

Writes item as a message.

fn compute_message_size(item: &mut T, sizer: MessageSizer<'_>)

Computes the size of item as a message.

impl<E> Copy for TransparentEncoding<E>

where E: Copy,
