Struct CommandSpec 

pub struct CommandSpec { /* private fields */ }

An executable and its argv arguments.

The program and arguments use OsString so a local harness can preserve platform-native command-line values. This type does not interpret shell syntax; callers that need a shell must put the shell executable and its arguments in the vector explicitly.

Implementations

impl CommandSpec

pub fn new(program: impl Into<OsString>) -> Result<Self, CommandError>

Creates a command with no arguments.

pub fn with_arg( self, argument: impl Into<OsString>, ) -> Result<Self, CommandError>

Adds one argv argument and returns the updated command.

pub fn with_args<I, S>(self, arguments: I) -> Result<Self, CommandError>

where I: IntoIterator<Item = S>, S: Into<OsString>,

Adds several argv arguments and returns the updated command.

pub fn program(&self) -> &OsStr

Returns the executable program.

pub fn args(&self) -> &[OsString]

Returns the arguments after the executable program.

pub fn into_parts(self) -> (OsString, Vec<OsString>)

Returns the executable and arguments as owned values.
