Type Alias void::coreprovider::fmt::Result

pub type Result = Result<(), Error>;

The type returned by formatter methods.

Examples

use std::fmt;

#[derive(Debug)]
struct Triangle {
    a: f32,
    b: f32,
    c: f32
}

impl fmt::Display for Triangle {
    fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {
        write!(f, "({}, {}, {})", self.a, self.b, self.c)
    }
}

let pythagorean_triple = Triangle { a: 3.0, b: 4.0, c: 5.0 };

assert_eq!(format!("{pythagorean_triple}"), "(3, 4, 5)");

Aliased Type

enum Result {
    Ok(()),
    Err(Error),
}

Variants

Ok(())

Contains the success value

Err(Error)

Contains the error value

Trait Implementations

impl<T, E> Debug for Result<T, E>where T: Debug, E: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<T, E> Ord for Result<T, E>where T: Ord, E: Ord,

fn cmp(&self, other: &Result<T, E>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl<T, E> PartialEq<Result<T, E>> for Result<T, E>where T: PartialEq<T>, E: PartialEq<E>,

fn eq(&self, other: &Result<T, E>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T, E> PartialOrd<Result<T, E>> for Result<T, E>where T: PartialOrd<T>, E: PartialOrd<E>,

fn partial_cmp(&self, other: &Result<T, E>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl<T, E> Eq for Result<T, E>where T: Eq, E: Eq,
