Struct cargo::util::context::de::ConfigMapAccess

struct ConfigMapAccess<'gctx> {
    de: Deserializer<'gctx>,
    fields: Vec<KeyKind>,
    field_index: usize,
}

Fields

de: Deserializer<'gctx>

fields: Vec<KeyKind>

The fields that this map should deserialize.

field_index: usize

Current field being deserialized.

Implementations

impl<'gctx> ConfigMapAccess<'gctx>

fn new_map( de: Deserializer<'gctx>, ) -> Result<ConfigMapAccess<'gctx>, ConfigError>

fn new_struct( de: Deserializer<'gctx>, given_fields: &'static [&'static str], ) -> Result<ConfigMapAccess<'gctx>, ConfigError>

Trait Implementations

impl<'de, 'gctx> MapAccess<'de> for ConfigMapAccess<'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.
