Trait Implementations§

source§

impl<'de, 'a, R: BufReader<'de>, K: DeserializeSeed<'de> + Clone, V: DeserializeSeed<'de> + Clone> MapAccess<'de> for MapAccess<'a, R, K, V>

§

type Key = <K as DeserializeSeed<'de>>::Output

The key type of the map.
§

type Value = <V as DeserializeSeed<'de>>::Output

The value type of the map.
§

type Error = DecodeError

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

fn next_entry( &mut self ) -> Result<Option<(Self::Key, Self::Value)>, Self::Error>

This returns Ok(Some((key, value))) for the next (key-value) pair in the map, or Ok(None) if there are no more remaining items.
source§

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

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