Enum RemoveError

pub enum RemoveError {
    IndexOutOfBounds {
        index: NonZeroUsize,
        len: NonZeroUsize,
    },
    WouldBecomeEmpty,
    Both {
        index: NonZeroUsize,
        len: NonZeroUsize,
    },
}

Available on crate feature alloc only.

Error returned when removing an element fails.

Variants

IndexOutOfBounds

The index is greater or equal to the number of elements.

Fields

index: NonZeroUsize

The index used for attempted access.

len: NonZeroUsize

The total number of elements stored.

WouldBecomeEmpty

Removing the element would leave an empty vec.

Both

Both the index is out of bounds and the vec would become empty after removing the element.

Fields

index: NonZeroUsize

The index used for attempted access.

len: NonZeroUsize

The total number of elements stored.

Implementations

impl RemoveError

pub fn is_oob(&self) -> bool

Returns true if there was out-of-bounds access.

Note that this also returns true for the Both variant.

pub fn is_would_become_empty(&self) -> bool

Returns true if the resulting vec would become empty after removing the element.

Note that this also returns true for the Both variant.

Trait Implementations

impl Clone for RemoveError

fn clone(&self) -> RemoveError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RemoveError

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

Formats the value using the given formatter.

impl Display for RemoveError

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

Formats the value using the given formatter.

impl Error for RemoveError

Available on crate feature std, or crate feature newer-rust and rust_version=">= 1.81" only.

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)

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