Trait serde::de::SeqAccess [] [src]

pub trait SeqAccess<'de> {
    type Error: Error;
    fn next_element_seed<T>(
        &mut self,
        seed: T
    ) -> Result<Option<T::Value>, Self::Error>
    where
        T: DeserializeSeed<'de>
; fn next_element<T>(&mut self) -> Result<Option<T>, Self::Error>
    where
        T: Deserialize<'de>
, { ... } fn size_hint(&self) -> Option<usize> { ... } }

Provides a Visitor access to each element of a sequence in the input.

This is a trait that a Deserializer passes to a Visitor implementation, which deserializes each item in a sequence.

Associated Types

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

Required Methods

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

Deserialize implementations should typically use SeqAcccess::next_element instead.

Provided Methods

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

This method exists as a convenience for Deserialize implementations. SeqAccess implementations should not override the default behavior.

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