Struct TypeView 

pub struct TypeView<'a> {
    pub name: &'a str,
    pub fields: RepeatedView<'a, FieldView<'a>>,
    pub oneofs: RepeatedView<'a, &'a str>,
    pub options: RepeatedView<'a, OptionView<'a>>,

    pub syntax: EnumValue<Syntax>,
    pub edition: &'a str,
    pub __buffa_unknown_fields: UnknownFieldsView<'a>,
}

A protocol buffer message type.

New usages of this message as an alternative to DescriptorProto are strongly discouraged. This message does not reliability preserve all information necessary to model the schema and preserve semantics. Instead make use of FileDescriptorSet which preserves the necessary information.

impl<'a> MessageView<'a> for TypeView<'a>

type Owned = Type

The corresponding owned message type.

fn decode_view(buf: &'a [u8]) -> Result<Self, DecodeError>

Decode a view from a buffer, borrowing string/bytes fields directly.

fn decode_view_with_ctx( buf: &'a [u8], ctx: DecodeContext<'_>, ) -> Result<Self, DecodeError>

Decode a view under custom decode limits.

fn merge_view_field( &mut self, tag: Tag, cur: &'a [u8], before_tag: &'a [u8], ctx: DecodeContext<'_>, ) -> Result<&'a [u8], DecodeError>

Decode one field’s payload into this view (generated per message).

fn to_owned_message(&self) -> Result<Type, DecodeError>

Convert this view to the owned message type.

fn to_owned_from_source( &self, __buffa_src: Option<&Bytes>, ) -> Result<Type, DecodeError>

Convert this view to the owned message type, optionally slicing bytes::Bytes-typed fields from source instead of copying.

fn decode_view_ctx( buf: &'a [u8], ctx: DecodeContext<'_>, ) -> Result<Self, DecodeError>

where Self: Default,

Decode a view under an explicit DecodeContext (remaining recursion depth, unknown-field allowance, and element-memory budget), driving the provided tag loop over merge_view_field.

fn merge_into_view( &mut self, buf: &'a [u8], ctx: DecodeContext<'_>, ) -> Result<(), DecodeError>

Merge fields from buf into this view (proto merge semantics): repeated fields append, singular fields last-wins, singular message fields merge recursively.

impl<'a> ReflectElement for TypeView<'a>

Available on crate feature reflect only.

fn as_value_ref(&self) -> ValueRef<'_>

Borrow this element as a ValueRef.

impl<'a> ReflectMessage for TypeView<'a>

Available on crate feature reflect only.

fn message_descriptor(&self) -> &MessageDescriptor

The descriptor for this message type.

fn pool(&self) -> &Arc<DescriptorPool>

The pool the descriptor lives in. Use this to dereference MessageIndex / EnumIndex from FieldKind, or Arc::clone it to construct sibling DynamicMessages while navigating nested fields.

fn get(&self, field: &FieldDescriptor) -> ValueRef<'_>

Get a field’s value.

fn has(&self, field: &FieldDescriptor) -> bool

Whether a field is present.

fn for_each_set(&self, f: &mut dyn FnMut(&FieldDescriptor, ValueRef<'_>))

Visit every set field.

fn to_dynamic(&self) -> DynamicMessage

Snapshot this message as an owned DynamicMessage.

fn unknown_fields(&self) -> &UnknownFields

The fields preserved from decode that the message’s descriptor does not recognize.

fn which_oneof(&self, oneof: &OneofDescriptor) -> Option<&FieldDescriptor>

Which member of oneof is set, if any.

impl<'a> ViewEncode<'a> for TypeView<'a>

fn compute_size(&self, __cache: &mut SizeCache) -> u32

Compute the encoded byte size of this view, recording nested sub-message sizes in cache for write_to to consume.

fn write_to(&self, __cache: &mut SizeCache, buf: &mut impl EncodeSink)

Write this view’s encoded bytes to a buffer, consuming nested-message sizes from cache (populated by a prior compute_size call on the same cache).

fn encode(&self, buf: &mut impl EncodeSink)

Compute size, then write. Primary view-encode entry point.

fn try_encode(&self, buf: &mut impl EncodeSink) -> Result<(), EncodeError>

Encode, returning an error instead of panicking if the encoded size exceeds the 2 GiB protobuf limit (MAX_MESSAGE_BYTES).

fn encode_with_cache(&self, cache: &mut SizeCache, buf: &mut impl EncodeSink)

Encode using a caller-supplied SizeCache, for reuse across many encodes in a hot loop. Clears the cache first.

fn try_encode_with_cache( &self, cache: &mut SizeCache, buf: &mut impl EncodeSink, ) -> Result<(), EncodeError>

Encode with a caller-supplied SizeCache, returning an error instead of panicking if the encoded size exceeds the 2 GiB protobuf limit (MAX_MESSAGE_BYTES). Clears the cache first.

fn try_encode_bounded( &self, max_bytes: u32, buf: &mut impl EncodeSink, ) -> Result<u32, EncodeError>

Encode this view into buf only if its encoded size fits within max_bytes, using a single size pass that is then reused for the write.

fn try_encode_bounded_with_cache( &self, max_bytes: u32, cache: &mut SizeCache, buf: &mut impl EncodeSink, ) -> Result<u32, EncodeError>

Like try_encode_bounded but reuses an existing SizeCache, clearing it first.

fn encoded_len(&self) -> u32

Compute the encoded byte size of this view.

fn try_encoded_len(&self) -> Result<u32, EncodeError>

Compute the encoded byte size, returning an error instead of panicking if it exceeds the 2 GiB protobuf limit (MAX_MESSAGE_BYTES).

fn encode_length_delimited(&self, buf: &mut impl EncodeSink)

Encode this view as a length-delimited byte sequence.

fn try_encode_length_delimited( &self, buf: &mut impl EncodeSink, ) -> Result<(), EncodeError>

Encode as a length-delimited byte sequence, returning an error instead of panicking if the encoded size exceeds the 2 GiB protobuf limit (MAX_MESSAGE_BYTES).

fn encode_to_vec(&self) -> Vec<u8>

Encode this view to a new Vec<u8>.

fn try_encode_to_vec(&self) -> Result<Vec<u8>, EncodeError>

Encode to a new Vec<u8>, returning an error instead of panicking if the encoded size exceeds the 2 GiB protobuf limit (MAX_MESSAGE_BYTES).

fn encode_to_bytes(&self) -> Bytes

Encode this view to a new bytes::Bytes.

fn try_encode_to_bytes(&self) -> Result<Bytes, EncodeError>

Encode to a new bytes::Bytes, returning an error instead of panicking if the encoded size exceeds the 2 GiB protobuf limit (MAX_MESSAGE_BYTES).

impl ViewReborrow for TypeView<'static>

type Reborrowed<'b> = TypeView<'b>

The same view type with its lifetime shortened to 'b.

fn reborrow<'b>(this: &'b Self) -> &'b Self::Reborrowed<'b>

Coerce &'b Self (= &'b FooView<'static>) to &'b Self::Reborrowed<'b> (= &'b FooView<'b>). The canonical body is just this; the compiler accepts it via standard lifetime variance for covariant view types.
