Trait ESExprVarArgCodec

pub trait ESExprVarArgCodec<'a>:
    ESExprEncodedEq
    + Sized
    + 'a {
    type Element: ESExprCodec<'a> + 'a;

    // Required methods
    fn encode_vararg_element(&'a self, args: &mut Vec<ESExpr<'a>>);
    fn decode_vararg_element(
        args: &mut VecDeque<ESExpr<'a>>,
        constructor_name: &str,
        start_index: &mut usize,
    ) -> Result<Self, DecodeError>;
}

A field codec for variable arguments.

Required Associated Types

type Element: ESExprCodec<'a> + 'a

The element type.

Required Methods

fn encode_vararg_element(&'a self, args: &mut Vec<ESExpr<'a>>)

Encode variable arguments

fn decode_vararg_element( args: &mut VecDeque<ESExpr<'a>>, constructor_name: &str, start_index: &mut usize, ) -> Result<Self, DecodeError>

Decode variable 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.
