Trait FlattenExtract 

pub trait FlattenExtract<P>: Send + Sync {
    type Item;

    // Required method
    fn extract<'s>(&self, parent: &'s P) -> &'s [Self::Item];
}

Required Associated Types

type Item

Required Methods

fn extract<'s>(&self, parent: &'s P) -> &'s [Self::Item]

Dyn Compatibility

This trait is dyn compatible.

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