Struct InferenceError 

#[non_exhaustive]
pub struct InferenceError { /* private fields */ }

Inference error including a kind and optional code.

Implementations

impl InferenceError

pub const fn new(kind: InferenceErrorKind, code: u32) -> Self

Construct a new inference error.

pub const fn kind(&self) -> &InferenceErrorKind

Return the inference error kind.

pub const fn code(&self) -> &u32

Return the numeric code associated with this inference error.

Trait Implementations

impl Clone for InferenceError

fn clone(&self) -> InferenceError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InferenceError

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

Formats the value using the given formatter.

impl Display for InferenceError

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

Formats the value using the given formatter.

impl Error for InferenceError

Available on crate feature std only.

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 InferenceError

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