Struct TermsError 

pub struct TermsError(/* private fields */);

What terms fails with: what Terms refuses, or the source’s own failure.

A source reports through Error::source whichever sink it feeds, so every failure arrives as a SourceError. term recovers a TermError from it, the same downcast a caller makes on EncryptError::Source when Terms runs beside encryption, and refusal a value refused for its shape, which encryption reports as EncryptError::Shape. source_error is the error as it arrived.

Implementations

impl TermsError

pub fn term(&self) -> Option<&TermError>

The scalar Terms refused, or None if the source failed on its own or the value was refused for its shape.

pub fn refusal(&self) -> Option<&Refusal>

The value refused for its shape, as encryption would refuse it, or None if it was refused for another reason.

pub fn source_error(&self) -> &SourceError

The failure as the walk reported it: what Terms refused, or the source’s own error.

Trait Implementations

impl Debug for TermsError

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

Formats the value using the given formatter.

impl Display for TermsError

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

Formats the value using the given formatter.

impl Error for TermsError

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 Error for TermsError

fn source(error: SourceError) -> Self

Wrap a failure that came from the source, not the sink.
