Struct validator_types::CustomArgument

pub struct CustomArgument {
    pub def_span: Span,
    pub arg_type: Type,
    pub arg_access: Option<Expr>,
}

This struct stores information about defined custom arguments that will be passed in by the user in the validation step.

Fields

def_span: Span

The span of type definition, this can be used in combination with quote_spanned! for better error reporting

arg_type: Type

The type of the argument. This can use 'v_a as a lifetime but has to be Sized. This means that the type size has to be known at compile time

arg_access: Option<Expr>

This is the way we can access the value from the provided arguments. This will usually look something like args.0.
