Trait FilterParameter 

pub trait FilterParameter<'map, 'elem: 'map>: Sealed {
    type Argument: FilterArgument<'map, 'elem>;

    // Required methods
    fn is_array() -> bool;
    fn is_optional() -> bool;
    fn get_from_map(map: &'map Map<'elem>, key: &str) -> Self;
}

An internal trait representing a filter parameter type (argument type + whether it’s an array or optional).

Required Associated Types

type Argument: FilterArgument<'map, 'elem>

The underlying argument type for this parameter type.

Required Methods

fn is_array() -> bool

Returns whether this parameter is an array.

fn is_optional() -> bool

Returns whether this parameter is optional.

fn get_from_map(map: &'map Map<'elem>, key: &str) -> Self

Retrieves this parameter from the given map.

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.
