Trait Implementations

impl<'a> Clone for ColumnView<'a>

fn clone(&self) -> ColumnView<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for ColumnView<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> Default for ColumnView<'a>

fn default() -> ColumnView<'a>

Returns the “default value” for a type.

impl<'v> DefaultViewInstance for ColumnView<'v>

fn default_view_instance<'a>() -> &'a Self

where Self: 'a,

Return a reference to the single default view instance.

impl<'a> MessageName for ColumnView<'a>

const PACKAGE: &'static str = "unitycatalog.tables.v1"

The protobuf package the message is declared in.

const NAME: &'static str = "Column"

The unqualified message name, with . between nesting levels.

const FULL_NAME: &'static str = "unitycatalog.tables.v1.Column"

The fully-qualified protobuf type name with no leading dot.

const TYPE_URL: &'static str = "type.googleapis.com/unitycatalog.tables.v1.Column"

The google.protobuf.Any.type_url form for this message.

impl<'a> MessageView<'a> for ColumnView<'a>

type Owned = Column

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_limit( buf: &'a [u8], depth: u32, ) -> Result<Self, DecodeError>

Decode a view with a custom recursion depth limit.

fn to_owned_message(&self) -> Column

Convert this view to the owned message type.

fn to_owned_from_source(&self, __buffa_src: Option<&Bytes>) -> Column

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

impl<'__a> Serialize for ColumnView<'__a>

Serializes this view as protobuf JSON.

Implicit-presence fields with default values are omitted, required fields are always emitted, explicit-presence (optional) fields are emitted only when set, bytes fields are base64-encoded, and enum values are their proto name strings.

This impl uses serialize_map(None) because the number of emitted fields depends on default-omission rules; serializers that require known map lengths (e.g. bincode) will return a runtime error. Use the owned message type for those formats.

fn serialize<__S: Serializer>(&self, __s: __S) -> Result<__S::Ok, __S::Error>

Serialize this value into the given Serde serializer.

impl<'a> ViewEncode<'a> for ColumnView<'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 BufMut)

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 BufMut)

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

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

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

fn encoded_len(&self) -> u32

Compute the encoded byte size of this view.

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

Encode this view as a length-delimited byte sequence.

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

Encode this view to a new Vec<u8>.

fn encode_to_bytes(&self) -> Bytes

Encode this view to a new bytes::Bytes.

impl ViewReborrow for ColumnView<'static>

type Reborrowed<'b> = ColumnView<'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.
