Enum ProcessError 

pub enum ProcessError {
    Spawn {
        program: PathBuf,
        source: Error,
    },
    Identity {
        pid: u32,

}

Something went wrong spawning, observing, or identifying a process.

Variants

Spawn

The program could not be launched.

Fields

program: PathBuf

The program that could not be launched.

source: Error

The underlying error.

Identity

The operating system would not say when a process started.

Fields

pid: u32

The process that could not be identified.

source: Error

The underlying error.

NoSuchProcess

No live process holds this PID, so it has no identity to record.

Fields

pid: u32

The PID that resolved to nothing.

Control

Waiting on, signalling, or killing a process failed.

Fields

pid: u32

The process that could not be controlled.

source: Error

The underlying error.

SecretInCommandLine

The handoff payload was about to be visible in a process listing.

Returned by SpawnSpec::spawn_with_handoff rather than logged, because the whole point is that the launch must not happen.

Fields

program: PathBuf

The program that would have been launched.

location: String

Where the payload was found — an argument index or an environment variable name.

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ProcessError

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

Returns 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.
