Struct zng::l10n::LangMap

pub struct LangMap<V> { /* private fields */ }

Trait Implementations

impl<V> Clone for LangMap<V>

where V: Clone,

fn clone(&self) -> LangMap<V>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<V> Debug for LangMap<V>

where V: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<V> Default for LangMap<V>

fn default() -> LangMap<V>

Returns the “default value” for a type.

impl<'de, V> Deserialize<'de> for LangMap<V>

where V: Deserialize<'de>,

fn deserialize<__D>( __deserializer: __D, ) -> Result<LangMap<V>, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<V> IntoIterator for LangMap<V>

type Item = (Lang, V)

The type of the elements being iterated over.

type IntoIter = IntoIter<(Lang, V)>

Which kind of iterator are we turning this into?

fn into_iter(self) -> <LangMap<V> as IntoIterator>::IntoIter

Creates an iterator from a value.

impl<V> PartialEq for LangMap<V>

where V: PartialEq,

fn eq(&self, other: &LangMap<V>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<V> Serialize for LangMap<V>

where V: Serialize,

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<V> Eq for LangMap<V>

where V: Eq,
