    },
    MappingUnavailable,
    MappingLockPoisoned,
    RangeOutOfBounds {

}

Errors returned by CPU access to a MetalBuffer.

Variants

CpuInaccessibleStorage

The buffer’s storage mode does not expose CPU-addressable bytes.

Fields

storage_mode: usize

MappingUnavailable

Metal did not provide a CPU mapping for an otherwise accessible buffer.

MappingLockPoisoned

Another mapping panicked while holding the allocation’s mapping lock.

RangeOutOfBounds

The requested byte range is outside the allocation.

Fields

offset: usize

length: usize

buffer_length: usize

InvalidRange

The supplied range has its end before its start.

ManagedStorageRequired

The operation requires managed storage.

Fields

storage_mode: usize

Trait Implementations

impl Clone for MetalBufferAccessError

fn clone(&self) -> MetalBufferAccessError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetalBufferAccessError

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

Formats the value using the given formatter.

impl Display for MetalBufferAccessError

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

Formats the value using the given formatter.

impl Eq for MetalBufferAccessError

impl Error for MetalBufferAccessError

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 PartialEq for MetalBufferAccessError

fn eq(&self, other: &MetalBufferAccessError) -> bool

Equality operator ==.

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

Inequality operator !=.
