Enum GetManyMutError

pub enum GetManyMutError {
    IndexOutOfBounds,
    OverlappingIndices,
}

🔬This is a nightly-only experimental API. (get_many_mut #104642)

The error type returned by get_many_mut.

It indicates one of two possible errors:

• An index is out-of-bounds.
• The same index appeared multiple times in the array (or different but overlapping indices when ranges are provided).

Examples

#![feature(get_many_mut)]
use std::slice::GetManyMutError;

let v = &mut [1, 2, 3];
assert_eq!(v.get_many_mut([0, 999]), Err(GetManyMutError::IndexOutOfBounds));
assert_eq!(v.get_many_mut([1, 1]), Err(GetManyMutError::OverlappingIndices));

Variants

IndexOutOfBounds

🔬This is a nightly-only experimental API. (get_many_mut #104642)

An index provided was out-of-bounds for the slice.

OverlappingIndices

🔬This is a nightly-only experimental API. (get_many_mut #104642)

Two indices provided were overlapping.

Trait Implementations

impl Clone for GetManyMutError

fn clone(&self) -> GetManyMutError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GetManyMutError

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

Formats the value using the given formatter.

impl Display for GetManyMutError

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

Formats the value using the given formatter.

impl Error for GetManyMutError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access #99301)

Provides type-based access to context intended for error reports.

impl PartialEq for GetManyMutError

fn eq(&self, other: &GetManyMutError) -> 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.
