Trait ConstantTimeResult

pub trait ConstantTimeResult<T, E> {
    // Required methods
    fn ct_is_ok(&self) -> bool;
    fn ct_is_err(&self) -> bool;
    fn ct_map<U, F, G>(self, ok_fn: F, err_fn: G) -> U
       where F: FnOnce(T) -> U,
             G: FnOnce(E) -> U,
             U: ConditionallySelectable;
}

Trait for checking if an operation succeeded in constant time

Required Methods

fn ct_is_ok(&self) -> bool

Check if this result is Ok, without branching on the result

fn ct_is_err(&self) -> bool

Check if this result is Err, without branching on the result

fn ct_map<U, F, G>(self, ok_fn: F, err_fn: G) -> U

where F: FnOnce(T) -> U, G: FnOnce(E) -> U, U: ConditionallySelectable,

Map a result to a value in constant time, calling a provided function regardless of whether the result is Ok or Err

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.
