Serializer

Drains using Format will internally use types implementing this trait.

Required methods

fn emit_arguments(&mut self, key: Key, val: &Arguments) -> Result

Emit fmt::Arguments

This is the only method that has to implemented, but for performance and to retain type information most serious Serializers will want to implement all other methods as well.

fn emit_serde(&mut self, key: Key, value: &dyn SerdeValue) -> Result

Emit a value implementing serde::Serialize

This is especially useful for composite values, eg. structs as Json values, or sequences.

To prevent pulling-in serde dependency, this is an extension behind a serde feature flag.

The value needs to implement SerdeValue.
