Trait Query

pub trait Query<T> {
    // Required method
    fn is_match(&self, t: &T) -> bool;

    // Provided method
    fn matching_elements<'a>(
        &self,
        a: impl IntoIterator<Item = &'a T>,
    ) -> Vec<&'a T> { ... }
}

A Query matches against elements of some kind,

Required Methods

fn is_match(&self, t: &T) -> bool

returns true if query is a match.

Provided Methods

fn matching_elements<'a>( &self, a: impl IntoIterator<Item = &'a T>, ) -> Vec<&'a T>

collects a vector of all elements that match the query.

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.
