Struct cargo_util::ProcessError

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

impl ProcessError

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.

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.

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

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

• cmd is usually but not limited to std::process::Command.

Trait Implementations

impl Debug for ProcessError

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

Formats the value using the given formatter.

impl Display for ProcessError

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

Formats the value using the given formatter.

impl Error for ProcessError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
