Enum PlanningError 

pub enum PlanningError {
    InvalidConfiguration {
        message: String,
    },
    RuntimeState {
        message: String,
    },
}

Domain-specific cause of an einsum planning failure.

Caller-controlled expressions, shapes, and optimizer options use PlanningError::InvalidConfiguration. Runtime-state classification is reserved for an unavailable or poisoned planner state.

Examples

use tenferro_einsum::{Error, PlanningError};

let error = Error::planning("the requested path is invalid");
assert!(matches!(
    error,
    Error::Planning {
        source: PlanningError::InvalidConfiguration { .. }
    }
));

Variants

InvalidConfiguration

The requested expression, path, or planner option is invalid.

Fields

message: String

Human-readable configuration detail.

RuntimeState

Planner state required by a valid request is unavailable.

Fields

message: String

Human-readable state detail.

Trait Implementations

impl Debug for PlanningError

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

Formats the value using the given formatter.

impl Display for PlanningError

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

Formats the value using the given formatter.

impl Error for PlanningError

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>)
