Enum TryReserveError 

pub enum TryReserveError {
    NotUnique,
    Unsupported,
    AllocError,
    CapacityOverflow,
}

Error which can occur when trying to reserve additional capacity for a mutable buffer.

Variants

NotUnique

The buffer reference is not unique.

Occurs when the same buffer is referenced by multiple ArcSliceMuts.

Unsupported

The buffer doesn’t support reservation.

AllocError

The memory allocator returned an error.

CapacityOverflow

The required capacity exceeds the buffer maximum (usually isize::MAX bytes).

Trait Implementations

impl Clone for TryReserveError

fn clone(&self) -> TryReserveError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TryReserveError

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

Formats the value using the given formatter.

impl Display for TryReserveError

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

Formats the value using the given formatter.

impl Error for TryReserveError

Available on crate feature std 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.

impl From<AllocError> for TryReserveError

fn from(_: AllocError) -> Self

Converts to this type from the input type.

impl PartialEq for TryReserveError

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