Struct CoverageGateError 

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

Top-level error returned from every fallible function in the cargo-coverage-gate library.

Carries no free-form fields — the specific cause is encoded in the chained source error (see the From impls). Callers surface the message verbatim through their own diagnostic surface; the Display rendering includes the chained source as Caused by: … automatically.

Trait Implementations

impl Debug for CoverageGateError

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

Formats the value using the given formatter.

impl Display for CoverageGateError

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

Formats the value using the given formatter.

impl Enrichable for CoverageGateError

fn add_enrichment(&mut self, entry: EnrichmentEntry)

Adds enrichment information to the error.

impl Error for CoverageGateError

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 ErrorExt for CoverageGateError

fn message(&self) -> String

Returns the formatted error message without backtrace.

fn backtrace(&self) -> &Backtrace

Returns a reference to the captured backtrace.

fn has_backtrace(&self) -> bool

Returns true if the error has a captured backtrace.

fn find_source<T>(&self) -> Option<&T>

where T: Error + 'static,

Finds the first source error of the specified type in the error chain.

fn find_source_with<T>(&self, search: impl Fn(&T) -> bool) -> Option<&T>

where T: Error + 'static,

Finds the first source error of the specified type that matches the given predicate.

impl From<!> for CoverageGateError

fn from(_value: Infallible) -> Self

Converts to this type from the input type.
