Expand description
View mapping emit functions. Used when implementing a view’s map()
function.
Required Methods§
sourcefn emit_key_and_value<K, Value>(
&self,
key: K,
value: Value
) -> Result<Mappings<K, Value>, Error>
fn emit_key_and_value<K, Value>( &self, key: K, value: Value ) -> Result<Mappings<K, Value>, Error>
Creates a Map
result with a key
and value
.
Provided Methods§
sourcefn emit_if(&self, condition: bool) -> Result<Mappings, Error>
fn emit_if(&self, condition: bool) -> Result<Mappings, Error>
Creates a Map
result with an empty key and value if condition
is
true.
