Enum OptimizerError 

pub enum OptimizerError {
    PostconditionFailed {
        pass: String,
        errors: Vec<GraphError>,
    },
    Ir(IrError),
    Fusion(String),
}

Crate-level error for the optimization pipeline.

Variants

PostconditionFailed

A pass left the graph in a structurally invalid state. Raised by the default OptimizationPass::postconditions check (debug builds).

Fields

pass: String

The pass whose postcondition failed.

errors: Vec<GraphError>

The structural defects found by graph.validate().

Ir(IrError)

A rewrite requested an operation the IR rejected.

Fusion(String)

A fusion could not be applied safely (e.g. malformed match).

Trait Implementations

impl Debug for OptimizerError

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

Formats the value using the given formatter.

impl Display for OptimizerError

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

Formats the value using the given formatter.

impl Error for OptimizerError

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<IrError> for OptimizerError

fn from(source: IrError) -> Self

Converts to this type from the input type.

impl From<Vec<GraphError>> for OptimizerError

fn from(errors: Vec<GraphError>) -> Self

Converts to this type from the input type.
