Trait serde::de::SeqVisitor [] [src]

pub trait SeqVisitor {
    type Error: Error;
    fn visit_seed<T>(
        &mut self,
        seed: T
    ) -> Result<Option<T::Value>, Self::Error>
    where
        T: DeserializeSeed
; fn visit<T>(&mut self) -> Result<Option<T>, Self::Error>
    where
        T: Deserialize
, { ... } fn size_hint(&self) -> (usize, Option<usize>) { ... } }

SeqVisitor visits each item in a sequence.

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 SeqVisitor::visit 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. SeqVisitor implementations should not override the default behavior.

Return the lower and upper bound of items remaining in the sequence.
