std::process::ExitStatus - Rust
Description: API documentation for the Rust `ExitStatus` struct in crate `std`.

# 1.0.0[−][src]Struct std::process::ExitStatus

    pub struct ExitStatus(_);

Describes the result of a process after it has terminated.

This `struct` is used to represent the exit status of a child process. Child processes are created via the `Command` struct and their exit status is exposed through the `status` method.

## Methods

### `impl ExitStatus`[src]

#### `pub fn success(&self) -> bool`[src]

Was termination successful? Signal termination is not considered a success, and success is defined as a zero exit status.

# Examples

    use std::process::Command;

    let status = Command::new("mkdir")
                         .arg("projects")
                         .status()
                         .expect("failed to execute mkdir");

    if status.success() {
        println!("'projects/' directory created");
    } else {
        println!("failed to create 'projects/' directory");
    }Run

#### `pub fn code(&self) -> Option<i32>`[src]

Returns the exit code of the process, if any.

On Unix, this will return `None` if the process was terminated by a signal; `std::os::unix` provides an extension trait for extracting the signal and other details from the `ExitStatus`.

# Examples

    use std::process::Command;

    let status = Command::new("mkdir")
                         .arg("projects")
                         .status()
                         .expect("failed to execute mkdir");

    match status.code() {
        Some(code) => println!("Exited with status code: {}", code),
        None       => println!("Process terminated by signal")
    }Run

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
