Trait Filterable

pub trait Filterable<'a>: Sized {
    type Meta: Meta<'a, Self>;

    // Required method
    fn get_meta() -> Self::Meta;
}

Available on crate feature filter only.

Something which can produce a description of how to filter it.

This is the main derivable trait from this file. A type implementing Filterable can provide an object, Meta, which describes its supported fields and their operators.

Required Associated Types

type Meta: Meta<'a, Self>

The type which can describe our fields and their operators.

Required Methods

fn get_meta() -> Self::Meta

Produce an instance of our Meta type.

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.
