pub fn kind(&self) -> &ErrorKind

Returns the source of the error.

pub fn location(&self) -> &LocationInModule

Returns the main span for this error.

pub fn aux_spans(&self) -> &[LocationInModule<AuxErrorInfo>]

Returns auxiliary spans for this error.

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)
