Struct PathSink 

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

A path sink tracks the current path during deserialization.

Implementations

impl<'a> PathSink<'a>

pub fn wrap(sink: &'a mut dyn Sink) -> PathSink<'a>

Wraps a sink.

pub fn wrap_ref(sink: SinkHandle<'a>) -> PathSink<'a>

Wraps a sink ref.

Trait Implementations

impl<'a> Sink for PathSink<'a>

fn atom( &mut self, atom: Atom<'_>, state: &DeserializerState<'_>, ) -> Result<(), Error>

Receives an Atom.

fn map(&mut self, state: &DeserializerState<'_>) -> Result<(), Error>

Begins the deserialization of a map.

fn seq(&mut self, state: &DeserializerState<'_>) -> Result<(), Error>

Begins the receiving process for sequences.

fn next_key( &mut self, state: &DeserializerState<'_>, ) -> Result<SinkHandle<'_>, Error>

Returns a sink for the next key in a map.

fn next_value( &mut self, state: &DeserializerState<'_>, ) -> Result<SinkHandle<'_>, Error>

Returns a sink for the next value in a map or sequence.

fn finish(&mut self, state: &DeserializerState<'_>) -> Result<(), Error>

Called after atom, map or `seq.

fn descriptor(&self) -> &dyn Descriptor

Returns a descriptor for this type.

fn expecting(&self) -> Cow<'_, str>

Utility method to return an expectation message that is used in error messages.

fn unexpected_atom( &mut self, atom: Atom<'_>, state: &DeserializerState<'_>, ) -> Result<(), Error>

Implements a default fallback handling for atoms.

fn value_for_key( &mut self, key: &str, state: &DeserializerState<'_>, ) -> Result<Option<SinkHandle<'_>>, Error>

Returns a value sink for a specific struct field.
