Trait CtFind 

pub trait CtFind<T: CtAssign> {
    // Required method
    fn ct_find<P>(&self, predicate: P) -> CtOption<T>
       where P: Fn(&T) -> Choice;
}

Constant-time equivalent of Iterator::find, which can search a collection by iterating over every element and applying the given predicate to each item, then selecting the first matching entry.

Required Methods

fn ct_find<P>(&self, predicate: P) -> CtOption<T>

where P: Fn(&T) -> Choice,

Iterate through every T item in &self, applying the given predicate which can select a specific item by returning Choice::TRUE.

The first item where predicate returns Choice::TRUE is selected, or the CtOption equivalent of None is returned if the predicate returns Choice::FALSE for all items.

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.
