Enum InferenceMethodError 

pub enum InferenceMethodError {
    WrongParentCount {
        method: InferenceMethod,
        rule: ParentCountRule,
        got: usize,
    },
    TooManyParents {
        method: InferenceMethod,
        limit: usize,
        got: usize,
    },
}

Errors from InferenceMethod::compute.

Variants

WrongParentCount

Parent count did not match the method’s ParentCountRule.

Fields

method: InferenceMethod

The method.

rule: ParentCountRule

The rule that was violated.

got: usize

Actual parent count supplied.

TooManyParents

Supplied parent count exceeds the u128 product capacity. Bounded at 8 for methods that compute a joint product across all parents; relaxing this requires a log-table implementation.

Fields

method: InferenceMethod

The method.

limit: usize

Maximum supported parent count.

got: usize

Actual parent count supplied.

Trait Implementations

impl Debug for InferenceMethodError

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

Formats the value using the given formatter.

impl Display for InferenceMethodError

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

Formats the value using the given formatter.

impl Error for InferenceMethodError

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 InferenceMethodError

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