Struct Display

#[repr(transparent)]
pub struct Display<'a, E: Error + ?Sized>(pub &'a E);

Wrap a reference to an Error to display its error chain with format!("{}").

Tuple Fields

0: &'a E

Implementations

impl<'a, E: Error + ?Sized> Display<'a, E>

pub const fn new(err: &'a E) -> Self

Return the wrapped reference.

Trait Implementations

impl<'a, E: Clone + Error + ?Sized> Clone for Display<'a, E>

fn clone(&self) -> Display<'a, E>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<E: Error + ?Sized> Debug for Display<'_, E>

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

Formats the value using the given formatter.

impl<E: Error + ?Sized> Display for Display<'_, E>

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

Formats the value using the given formatter.

impl<'a, E: Error> From<&'a E> for Display<'a, E>

fn from(value: &'a E) -> Self

Converts to this type from the input type.

impl<'a, E: Hash + Error + ?Sized> Hash for Display<'a, E>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a, E: Ord + Error + ?Sized> Ord for Display<'a, E>

fn cmp(&self, other: &Display<'a, E>) -> Ordering

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'a, E: PartialEq + Error + ?Sized> PartialEq for Display<'a, E>

fn eq(&self, other: &Display<'a, E>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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

impl<'a, E: PartialOrd + Error + ?Sized> PartialOrd for Display<'a, E>

fn partial_cmp(&self, other: &Display<'a, E>) -> Option<Ordering>

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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