Struct conch_runtime::spawn::builtin::Shift

pub struct Shift<I> { /* fields omitted */ }

Represents a shift builtin command.

The shift builtin command will shift all shell or function positional arguments up by the specified amount. For example, shifting by 2 will result in $1 holding the previous value of $3, $2 holding the previous value of $4, and so on.

Trait Implementations

impl<I: Debug> Debug for Shift<I>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<I: PartialEq> PartialEq for Shift<I>

fn eq(&self, __arg_0: &Shift<I>) -> bool

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

fn ne(&self, __arg_0: &Shift<I>) -> bool

This method tests for !=.

impl<I: Eq> Eq for Shift<I>

impl<I: Clone> Clone for Shift<I>

fn clone(&self) -> Shift<I>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T, I, E: ?Sized> Spawn<E> for Shift<I> where
    T: StringWrapper,
    I: Iterator<Item = T>,
    E: ArgumentsEnvironment + ShiftArgumentsEnvironment + ReportErrorEnvironment, 

type EnvFuture = SpawnedShift<I>

The future that represents spawning the command.

type Future = ExitStatus

The future that represents the exit status of a fully bootstrapped command, which no longer requires an environment to be driven to completion.

type Error = Void

The type of error that a future will resolve with if it fails in a normal fashion.

fn spawn(self, _env: &E) -> Self::EnvFuture

Spawn the command as a future.
