Enum Error 

#[non_exhaustive]
pub enum Error {
    NotFound,
    Unusable(Unusable),
}

Reason why the command search did not yield a target

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.

NotFound

No command was found with the given name.

Unusable(Unusable)

A built-in was found, but it cannot be executed.

Note that the shell must not fall back to an external utility in this case: the built-in was found, so the command search is over.

Implementations

impl Error

pub const fn exit_status(self) -> ExitStatus

Returns the exit status the shell should produce for this error.

This is 127 if no command was found, and the Unusable::exit_status if a built-in was found but cannot be executed.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Error

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

Describes the reason without naming the command.

The result is a sentence fragment meant to be embedded in an error message that identifies the command, so it does not mention the name itself.

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

Formats the value using the given formatter.

impl Eq for Error

impl From<Unusable> for Error

fn from(unusable: Unusable) -> Self

Converts to this type from the input type.

impl Hash for Error

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Error

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

Equality operator ==.

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

Inequality operator !=.
