Struct ValueDeserializer 

struct ValueDeserializer<'gctx> {
    hits: u32,
    source: ValueSource<'gctx>,
}

This is a deserializer that deserializes into a Value<T> for configuration.

This is a special deserializer because it deserializes one of its struct fields into the location that this configuration value was defined in.

See more comments in value.rs for the protocol used here.

Fields

hits: u32

source: ValueSource<'gctx>

Implementations

impl<'gctx> ValueDeserializer<'gctx>

fn new(de: Deserializer<'gctx>) -> Result<ValueDeserializer<'gctx>, ConfigError>

fn with_cv(cv: CV) -> ValueDeserializer<'gctx>

fn definition(&self) -> &Definition

Trait Implementations

impl<'de, 'gctx> MapAccess<'de> for ValueDeserializer<'gctx>

type Error = ConfigError

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

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

where K: DeserializeSeed<'de>,

This returns Ok(Some(key)) for the next key in the map, or Ok(None) if there are no more remaining entries.

fn next_value_seed<V>(&mut self, seed: V) -> Result<V::Value, Self::Error>

where V: DeserializeSeed<'de>,

This returns a Ok(value) for the next value in the map.

fn next_entry_seed<K, V>( &mut self, kseed: K, vseed: V, ) -> Result<Option<(<K as DeserializeSeed<'de>>::Value, <V as DeserializeSeed<'de>>::Value)>, Self::Error>

where K: DeserializeSeed<'de>, V: DeserializeSeed<'de>,

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.

fn next_key<K>(&mut self) -> Result<Option<K>, Self::Error>

where K: Deserialize<'de>,

This returns Ok(Some(key)) for the next key in the map, or Ok(None) if there are no more remaining entries.

fn next_value<V>(&mut self) -> Result<V, Self::Error>

where V: Deserialize<'de>,

This returns a Ok(value) for the next value in the map.

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

where K: Deserialize<'de>, V: Deserialize<'de>,

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.

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

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
