Trait frunk::validated::IntoValidated

pub trait IntoValidated<T, E> {
    fn into_validated(self) -> Validated<HCons<T, HNil>, E>;
}

Trait for “lifting” a given type into a Validated

Required Methods

fn into_validated(self) -> Validated<HCons<T, HNil>, E>

Consumes the current Result into a Validated so that we can begin chaining

Examples

use frunk::prelude::*; // IntoValidated is in the prelude

let r1: Result<String, i32> = Result::Err(32);
let v = r1.into_validated();
assert!(v.is_err());
