Expand description

Needs to be implemented by everything that wants to be a LineSearchCondition

Required Methods§

Source

fn eval( &self, cur_cost: F, cur_grad: T, init_cost: F, init_grad: T, search_direction: T, alpha: F, ) -> bool

Evaluate the condition

Source

fn requires_cur_grad(&self) -> bool

Indicates whether this condition requires the computation of the gradient at the new point

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.
