Errors raised before an invalid Metal operation reaches the native API.

Variants

SwiftIntOverflow

A Rust usize cannot be represented by Swift’s signed Int.

Fields

argument: &'static str

Argument name.

value: usize

Rejected value.

IndexOutOfRange

A binding index exceeds the native slot count.

Fields

argument: &'static str

Argument name.

index: usize

Rejected index.

max_exclusive: usize

Exclusive upper bound.

NativeCallRejected

The Swift bridge rejected an operation after defensive validation.

Fields

operation: &'static str

Operation name.

CommandBufferAlreadyCommitted

The command buffer was already committed.

CommandBufferHasActiveEncoder

A command encoder is still active on the command buffer.

RenderEncoderAlreadyActive

The command buffer already has an active render encoder.

RenderEncoderCreationFailed

Native render-encoder creation failed.

RenderEncoderEnded

The render encoder has already ended.

UnknownPixelFormat

Fields

raw: u64

Trait Implementations

impl Clone for MetalError

fn clone(&self) -> MetalError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetalError

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

Formats the value using the given formatter.

impl Display for MetalError

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

Formats the value using the given formatter.

impl Eq for MetalError

impl Error for MetalError

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 MetalError

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