Enum Error 

#[non_exhaustive]
pub enum Error {
    StdinNotPiped,
    KilledBySignal,
    NonZeroExitCode(i32),
    Input(Error),
    Output(Error),

    Wait(Error),
}

An error raised by xstream

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

StdinNotPiped

The stdin to a child process wasn’t piped

KilledBySignal

One of the spawned processes was killed by a signal

NonZeroExitCode(i32)

One of the spawned processes returned a non-zero exit code

Input(Error)

An error occured while trying to read from the input

Output(Error)

An error occured while trying to write to a child process

Spawn(Error)

An error occured while trying to spawn a child process

Wait(Error)

An error occured while trying to wait for a child process

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
