Struct CommandLine 

pub struct CommandLine { /* private fields */ }

Convenient container for commandlines to execute in an crate::env::Environment.

Implementations

impl CommandLine

pub fn new<S: Clone + Into<String>>(cmd: &[S]) -> Self

Create a new instance of CommandLine.

The given slice must contain at least one entry, otherwise a runtime error occurs.

pub fn is_empty(&self) -> bool

True if nothing has been added to the commandline yet.

pub fn privileged(self) -> Self

Request privileges for CommandLine on-the-fly.

See CommandLine::needs_privileges.

pub fn needs_privileges(&mut self, yesno: bool)

Control whether privileges are needed to execute the command.

Privilege escalation is handled by each respective crate::env::Environment and on Unix systems usually refers to some way of executing commands as the root user.

pub fn get_privileged(&self) -> bool

pub fn is_interactive(&mut self, yesno: bool)

Control whether command execution should be interactive.

pub fn get_interactive(&self) -> bool

pub fn append<S: Clone + Into<String>>(&mut self, args: &[S])

Append arguments to an existing commandline.

pub fn command(&self) -> String

Obtain the command (first “chunk”) of the commandline.

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

Obtain the arguments of the commandline.

Returns an empty slice if there are no arguments in the command line.

Trait Implementations

impl Clone for CommandLine

fn clone(&self) -> CommandLine

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CommandLine

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

Formats the value using the given formatter.

impl Default for CommandLine

fn default() -> CommandLine

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CommandLine

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CommandLine

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

Formats the value using the given formatter.

impl<S: Clone + Into<String>> From<Vec<S>> for CommandLine

fn from(value: Vec<S>) -> Self

Converts to this type from the input type.

impl PartialEq for CommandLine

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

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

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

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

impl Serialize for CommandLine

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
