Trait Pick

pub trait Pick<O>: Sealed {
    // Required methods
    fn pick(self, when_true: O, when_false: O) -> O;
    fn pick_lazy<P, N>(self, when_true: P, when_false: N) -> O
       where P: FnOnce() -> O,
             N: FnOnce() -> O;
}

Required Methods

fn pick(self, when_true: O, when_false: O) -> O

fn pick_lazy<P, N>(self, when_true: P, when_false: N) -> O

where P: FnOnce() -> O, N: FnOnce() -> O,

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.

Implementations on Foreign Types

impl<O> Pick<O> for bool

fn pick(self: bool, when_true: O, when_false: O) -> O

Example:

use conditional_assignment::Pick;
let condition = 0 < 1;
let outcome = if condition {
   "true"
} else {
   "false"
};

fn pick_lazy<P, N>(self: bool, when_true: P, when_false: N) -> O

where P: FnOnce() -> O, N: FnOnce() -> O,

Example:

use conditional_assignment::Pick;
let condition = 0 < 1;
let outcome = condition.pick_lazy(
    || {
        assert!(condition);
        "true"
    },
    || {
        assert!(!condition);
        "false"
    },
);
