Unified error type for all Metal GPU operations.

Variants

DeviceNotFound

No Metal-capable GPU device was found on this system.

CommandBufferError(String)

A Metal command buffer completed with an error status.

ShaderCompilationError

An MSL shader failed to compile.

Fields

name: String

Name of the shader / kernel function that failed.

message: String

Compiler diagnostic message.

BufferAllocationError

Metal buffer allocation failed (usually out of GPU memory).

Fields

bytes: usize

Requested allocation size in bytes.

InvalidArgument(String)

An argument to a public function was invalid.

KernelNotFound(String)

A kernel function was not found in the compiled library.

IoError(String)

An I/O error occurred (e.g. reading a safetensors file).

SafetensorsError(String)

A safetensors file could not be parsed or contains invalid data.

QuantConfigError(String)

A quantization config file could not be parsed.

UnsupportedDtype(String)

An unsupported data type was encountered.

GgufParseError(String)

A GGUF file could not be parsed or contains invalid data.

Implementations

impl MlxError

Display implementation is handled by thiserror; this is a manual Debug helper for the shader variant to keep log output readable.

pub fn is_transient(&self) -> bool

Returns true if this is a transient error that might succeed on retry (e.g. a command buffer timeout). Most errors are permanent.

Trait Implementations

impl Debug for MlxError

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

Formats the value using the given formatter.

impl Display for MlxError

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

Formats the value using the given formatter.

impl Error for MlxError

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.
