Struct procspawn::Builder

pub struct Builder { /* fields omitted */ }

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.

Methods

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 + for<'de> Deserialize<'de>, R: Serialize + for<'de> Deserialize<'de>>(
    &mut self,
    args: A,
    func: fn(_: A) -> R
) -> JoinHandle<R>

Spawns the process.
