Enum StepPatternError 

#[non_exhaustive]
pub enum StepPatternError {
    PlaceholderSyntax(PlaceholderSyntaxError),
    InvalidPattern(Error),
}

Errors that may occur when compiling a [StepPattern].

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

PlaceholderSyntax(PlaceholderSyntaxError)

Placeholder syntax in the pattern is invalid.

InvalidPattern(Error)

The generated regular expression failed to compile.

Trait Implementations

impl Debug for StepPatternError

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

Formats the value using the given formatter.

impl Display for StepPatternError

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

Formats the value using the given formatter.

impl Error for StepPatternError

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.
