Struct KeySpans 

pub struct KeySpans { /* private fields */ }

Available on crate feature serde only.

KeySpans associates nested values with their full path from the first value as a Vec of Strings.

Sequence indices are also turned into strings.

Keys that cannot be represented as strings will be replaced by ???.

Trait Implementations

impl Clone for KeySpans

fn clone(&self) -> KeySpans

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for KeySpans

fn default() -> KeySpans

Returns the “default value” for a type.

impl Spans for KeySpans

type Span = Keys

The span type that is associated with each value.

fn key<S: ?Sized + Serialize>(&mut self, key: &S) -> NewSpan<Self::Span>

Span for a map key.

fn value<S: ?Sized + Serialize>(&mut self, _value: &S) -> NewSpan<Self::Span>

Span for a value.

fn unit(&mut self) -> NewSpan<Self::Span>

Same as value but for unit types.

fn map_start(&mut self) -> NewSpan<Self::Span>

Span for a map value.

fn map_end(&mut self) -> NewSpan<Self::Span>

Span for errors before closing a map.

fn seq_start(&mut self) -> NewSpan<Self::Span>

Span for a sequence value.

fn seq_end(&mut self) -> NewSpan<Self::Span>

Span for errors before closing a sequence.

fn descend(&self) -> Self

This is called when the validator enters a map member or a sequence element.
