Struct grep_matcher::NoError

pub struct NoError(_);

NoError provides an error type for matchers that never produce errors.

This error type implements the std::error::Error and fmt::Display traits for use in matcher implementations that can never produce errors.

The fmt::Debug and fmt::Display impls for this type panics.

Trait Implementations

impl Debug for NoError

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

Formats the value using the given formatter.

impl Eq for NoError

impl PartialEq for NoError

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

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

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

This method tests for !=.

impl Error for NoError

fn description(&self) -> &str

This method is soft-deprecated.

fn cause(&self) -> Option<&Error>

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

impl Display for NoError

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

Formats the value using the given formatter.

impl From<NoError> for Error

fn from(_: NoError) -> Error

Performs the conversion.
