pub struct ProcessError {
    pub desc: String,
    pub code: Option<i32>,
    pub stdout: Option<Vec<u8>>,
    pub stderr: Option<Vec<u8>>,
}

Fields§

§desc: String

A detailed description to show to the user why the process failed.

§code: Option<i32>

The exit status of the process.

This can be None if the process failed to launch (like process not found) or if the exit status wasn’t a code but was instead something like termination via a signal.

§stdout: Option<Vec<u8>>

The stdout from the process.

This can be None if the process failed to launch, or the output was not captured.

§stderr: Option<Vec<u8>>

The stderr from the process.

This can be None if the process failed to launch, or the output was not captured.

Implementations§

source§

impl ProcessError

source

pub fn new( msg: &str, status: Option<ExitStatus>, output: Option<&Output> ) -> ProcessError

Creates a new ProcessError.

  • status can be None if the process did not launch.
  • output can be None if the process did not launch, or output was not captured.
source

pub fn new_raw( msg: &str, code: Option<i32>, status: &str, stdout: Option<&[u8]>, stderr: Option<&[u8]> ) -> ProcessError

Creates a new ProcessError with the raw output data.

  • code can be None for situations like being killed by a signal on unix.
source

pub fn could_not_execute(cmd: impl Display) -> ProcessError

Creates a ProcessError with “could not execute process {cmd}”.
