OptionCodec

impulse_ui_kit::prelude::codee::string

Struct OptionCodec 

Source 
pub struct OptionCodec<C>(/* private fields */);
Expand description

Wraps a string codec that encodes T to create a codec that encodes Option<T>.

Example:

let original_value = Some(4);
let encoded = OptionCodec::<FromToStringCodec>::encode(&original_value).unwrap();
let decoded = OptionCodec::<FromToStringCodec>::decode(&encoded).unwrap();

assert_eq!(decoded, original_value);
