Trait ESExprDictCodec

pub trait ESExprDictCodec<'a>
where
    Self: Sized + 'a,
{
    type Element: ESExprCodec<'a> + 'a;

    // Required methods
    fn encode_dict_element(
        &'a self,
        kwargs: &mut BTreeMap<CowStr<'a>, ESExpr<'a>>,
    );
    fn decode_dict_element(
        kwargs: &mut BTreeMap<CowStr<'a>, ESExpr<'a>>,
        constructor_name: &str,
    ) -> Result<Self, DecodeError>;
}

A field codec for dictionary arguments.

Required Associated Types

type Element: ESExprCodec<'a> + 'a

The element type.

Required Methods

fn encode_dict_element(&'a self, kwargs: &mut BTreeMap<CowStr<'a>, ESExpr<'a>>)

Encode dictionary arguments.

fn decode_dict_element( kwargs: &mut BTreeMap<CowStr<'a>, ESExpr<'a>>, constructor_name: &str, ) -> Result<Self, DecodeError>

Decode dictionary arguments.

Errors

Will return Err if decoding fails.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
