Trait Implementations

impl<'de, A, B, E> SeqAccess<'de> for PairVisitor<A, B, E>

where A: IntoDeserializer<'de, E>, B: IntoDeserializer<'de, E>, E: Error,

type Error = E

The error type that can be returned if some error occurs during deserialization.

fn next_element_seed<T>( &mut self, seed: T, ) -> Result<Option<T::Value>, Self::Error>

where T: DeserializeSeed<'de>,

This returns Ok(Some(value)) for the next value in the sequence, or Ok(None) if there are no more remaining items.

fn size_hint(&self) -> Option<usize>

Returns the number of elements remaining in the sequence, if known.

fn next_element<T>(&mut self) -> Result<Option<T>, Self::Error>

where T: Deserialize<'de>,

This returns Ok(Some(value)) for the next value in the sequence, or Ok(None) if there are no more remaining items.
