Enum ResolveError 

pub enum ResolveError {
    Conflict {
        pseudo: PseudoType,
        first: DataType,
        other: DataType,
    },
    NonArrayGotArray,
    ArrayGotScalar,
    ArityMismatch {
        expected: usize,
        got: usize,
    },
}

Errors raised during polymorphic resolution.

Variants

Conflict

Two positions of the same pseudo-type resolved to conflicting concrete types.

Fields

pseudo: PseudoType

first: DataType

other: DataType

NonArrayGotArray

AnyNonArray matched against an array type.

ArrayGotScalar

AnyArray matched against a non-array type.

ArityMismatch

The signature’s arity doesn’t match the call site.

Fields

expected: usize

got: usize

Trait Implementations

impl Clone for ResolveError

fn clone(&self) -> ResolveError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ResolveError

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

Formats the value using the given formatter.

impl Display for ResolveError

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

Formats the value using the given formatter.

impl Error for ResolveError

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.
