Trait Filter 

pub trait Filter<Arg, Res>:
    Sync
    + Send
    + 'static
where
    Res: FunctionResult,
{
    // Required method
    fn call(&self, value: Arg, kwargs: Kwargs, state: &State<'_>) -> Res;

    // Provided method
    fn is_safe(&self) -> bool { ... }
}

The filter function type definition

Required Methods

fn call(&self, value: Arg, kwargs: Kwargs, state: &State<'_>) -> Res

The filter function type definition

Provided Methods

fn is_safe(&self) -> bool

Whether the current filter’s output should be treated as safe, defaults to false Only needs to be defined if the filter returns a string

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
