Struct Command

pub struct Command { /* private fields */ }

There’s a lot of common manipulation of what we think of as a command. This type factors out some of that, specifically:

• conversion from an arbitrary sequence of strings
• conversion to async_process’s builder type
• debugging representation

Implementations

impl Command

pub fn new<T: Into<OsString>>(command: T) -> Self

Constructs a new Command from a program or command name.

pub fn with_args<T>(self, args: T) -> Self

where T: IntoIterator, T::Item: Into<OsString>,

Adds a sequence of arguments to the command. The trait bound for T is:

T where
    T: IntoIterator,
    T::Item: Into<OsString>

…and can be understood as:

• T is anything that can turn into an iterator
• the iterator items are anything that can turn into an OsString

Commonly this might be a Vec<String> or just [&str].

Trait Implementations

impl Clone for Command

fn clone(&self) -> Command

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Command

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

Formats the command as it would appear on the command line. No fancy escaping or anything is done, this is purely for reading in the logs.

impl From<Command> for Command

fn from(command: Command) -> Self

Converts our Command type to an async_process::Command.
