Enum grok::Error

#[non_exhaustive]
pub enum Error {
    RecursionTooDeep,
    CompiledPatternIsEmpty(String),
    DefinitionNotFound(String),
    RegexCompilationFailed(String),
    GenericCompilationFailure(String),
}

Errors that can occur when using this library.

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.

RecursionTooDeep

The recursion while compiling has exhausted the limit.

CompiledPatternIsEmpty(String)

After compiling, the resulting compiled regex pattern is empty.

DefinitionNotFound(String)

A corresponding pattern definition could not be found for the given name.

RegexCompilationFailed(String)

If the compilation for a specific regex in the underlying engine failed.

GenericCompilationFailure(String)

Something is messed up during the compilation phase.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn StdError>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

impl PartialEq<Error> for Error

fn eq(&self, other: &Error) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Error) -> bool

This method tests for !=.
