Enum KernelMatch 

pub enum KernelMatch {
    Supported {
        cost: Cost,
        required_input_layouts: Option<Vec<TensorLayout>>,
        output_layouts: Vec<TensorLayout>,
    },
    Unsupported {
        reason: Cow<'static, str>,
    },
}

Result of crate::ExecutionProvider::supports_op.

A decline reason travels with the decision that produced it. EPs must not maintain a separate reason table: colocating the reason with Unsupported keeps diagnostics from drifting away from the actual claim predicate.

Variants

Supported

Fields

cost: Cost

required_input_layouts: Option<Vec<TensorLayout>>

Layouts the kernel requires for each input, if constrained.

output_layouts: Vec<TensorLayout>

Layouts the kernel produces for each output.

Unsupported

Fields

reason: Cow<'static, str>

Actionable explanation of what the EP accepts or how to fix fallback.

Implementations

impl KernelMatch

pub fn unsupported(reason: impl Into<Cow<'static, str>>) -> Self

Construct an unsupported match with its actionable decline reason.

pub fn is_supported(&self) -> bool

Whether the op is supported.

pub fn reason(&self) -> Option<&str>

The EP’s decline reason, or None when the op is supported.
