Struct Builder

pub struct Builder { /* private fields */ }

Process factory, which can be used in order to configure the properties of a process being created.

Methods can be chained on it in order to configure it.

Implementations

impl Builder

pub fn new() -> Self

Generates the base configuration for spawning a thread, from which configuration methods can be chained.

pub fn env<K, V>(&mut self, key: K, val: V) -> &mut Self

where K: AsRef<OsStr>, V: AsRef<OsStr>,

Set an environment variable in the spawned process.

Equivalent to Command::env

pub fn envs<I, K, V>(&mut self, vars: I) -> &mut Self

where I: IntoIterator<Item = (K, V)>, K: AsRef<OsStr>, V: AsRef<OsStr>,

Set environment variables in the spawned process.

Equivalent to Command::envs

pub fn env_remove<K: AsRef<OsStr>>(&mut self, key: K) -> &mut Self

Removes an environment variable in the spawned process.

Equivalent to Command::env_remove

pub fn env_clear(&mut self) -> &mut Self

Clears all environment variables in the spawned process.

Equivalent to Command::env_clear

pub fn stdin<T: Into<Stdio>>(&mut self, cfg: T) -> &mut Self

Captures the stdin of the spawned process, allowing you to manually send data via JoinHandle::stdin

pub fn stdout<T: Into<Stdio>>(&mut self, cfg: T) -> &mut Self

Captures the stdout of the spawned process, allowing you to manually receive data via JoinHandle::stdout

pub fn stderr<T: Into<Stdio>>(&mut self, cfg: T) -> &mut Self

Captures the stderr of the spawned process, allowing you to manually receive data via JoinHandle::stderr

pub fn spawn<A: Serialize + DeserializeOwned, R: Serialize + DeserializeOwned>( &mut self, args: A, func: fn(A) -> R, ) -> JoinHandle<R>

Spawns the process.

Trait Implementations

impl Debug for Builder

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

Formats the value using the given formatter.

impl Default for Builder

fn default() -> Builder

Returns the “default value” for a type.
