Struct UnknownFieldsView 

pub struct UnknownFieldsView<'a> { /* private fields */ }

A borrowed view of unknown fields.

Stores raw byte slices from the input buffer rather than decoded values, enabling zero-copy round-tripping of unknown fields.

Implementations

impl<'a> UnknownFieldsView<'a>

pub fn new() -> Self

Creates an empty view.

pub fn is_empty(&self) -> bool

Returns true if no unknown fields were recorded.

pub fn encoded_len(&self) -> usize

Total byte length of all unknown field data.

pub fn to_owned(&self) -> Result<UnknownFields, DecodeError>

Convert to an owned UnknownFields by parsing all stored raw byte spans.

Each span is a complete (tag + value) record as it appeared on the wire. Parsing uses crate::encoding::decode_unknown_field with the full recursion limit so deeply nested group fields are handled correctly.

Errors

Returns Err if any stored span is malformed — which should not occur when the view was produced by decode_view from valid wire data.

Trait Implementations

impl<'a> Clone for UnknownFieldsView<'a>

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

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

Performs copy-assignment from source.

impl<'a> Debug for UnknownFieldsView<'a>

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

Formats the value using the given formatter.

impl<'a> Default for UnknownFieldsView<'a>

fn default() -> UnknownFieldsView<'a>

Returns the “default value” for a type.
