Enum ChildSpecError 

pub enum ChildSpecError {
    EmptyArgv,
    EmptyProgram,
    EmptyEnvKey,
    EnvKeyContainsSeparator,
    Unrepresentable {
        what: &'static str,
    },
}

Why a set of process arguments is not a program the operating system can run.

Variants

EmptyArgv

The argv had no elements, so there was no program to run.

EmptyProgram

The program name was empty.

EmptyEnvKey

An environment key was empty.

EnvKeyContainsSeparator

An environment key contained =, which is the separator a key may not contain.

Unrepresentable

A value contained a NUL, which terminates the string before the kernel ever sees it.

Fields

what: &'static str

Which of the spec’s fields was rejected.

Trait Implementations

impl Clone for ChildSpecError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ChildSpecError

impl Eq for ChildSpecError

impl Error for ChildSpecError

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.

impl PartialEq for ChildSpecError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
