Enum CommandError

pub enum CommandError {
    InvalidCommand(String),
    InvalidArgument,
    InvalidRange,
    ParseFailed(String),
    Error(String),
}

Errors that can be encountered during command processing.

Variants

InvalidCommand(String)

Error for unmapped commands.

InvalidArgument

Error for bad command arguments.

InvalidRange

Error for bad ranges.

ParseFailed(String)

Error for command parse failures.

Error(String)

Generic error.

Trait Implementations

impl Debug for CommandError

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

Formats the value using the given formatter.

impl Display for CommandError

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

Formats the value using the given formatter.

impl Error for CommandError

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<I> From<CommandError> for UIError<I>

where I: ApplicationInfo,

fn from(source: CommandError) -> Self

Converts to this type from the input type.

impl PartialEq for CommandError

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

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

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

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