Struct ParseCommandError 

pub struct ParseCommandError(pub Cow<'static, str>);

Raised by either Commander or a NamedCommandParser if the supplied string slice could not be parsed into a valid Command object.

Tuple Fields

0: Cow<'static, str>

Implementations

impl ParseCommandError

pub fn convert<E: ToString>(err: E) -> Self

Converts anything representable as a String into a ParseCommandError, consuming the original. This is mostly used in error conversion; e.g., in Result::map_err().

Trait Implementations

impl Clone for ParseCommandError

fn clone(&self) -> ParseCommandError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseCommandError

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

Formats the value using the given formatter.

impl Display for ParseCommandError

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

Formats the value using the given formatter.

impl Error for ParseCommandError

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 PartialEq for ParseCommandError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
