Trait xso::TextCodec

pub trait TextCodec<T> {
    // Required methods
    fn decode(s: &str) -> Result<T, Error>;
    fn encode(value: T) -> Option<String>;
}

Represent a way to encode/decode text data into a Rust type.

This trait is used to specify how a given type is serialised into and from a string. This bypasses the FromXmlText / IntoXmlText traits, allowing to hide the specific implementation for transforming data from text into Rust types (and back) from a container’s public interface.

Required Methods

fn decode(s: &str) -> Result<T, Error>

Decode a string value into the type.

fn encode(value: T) -> Option<String>

Encode the type as string value.

If this returns None, the string value is not emitted at all.

Object Safety

This trait is not object safe.
