Enum CmdLineError 

#[non_exhaustive]
pub enum CmdLineError {
    LineBreak {
        index: usize,
    },
    Nul {
        index: usize,
    },
    ScriptPath,
}

An argument that cannot be carried through cmd.exe at all.

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.

LineBreak

The argument contained a carriage return or line feed.

Both terminate a cmd.exe command line. There is no quoting or escape that survives, so the argument is refused rather than truncated.

Fields

index: usize

Position of the offending argument, counting the program as 0.

Nul

The argument contained a NUL, which no Windows API accepts.

Fields

index: usize

Position of the offending argument, counting the program as 0.

ScriptPath

The resolved script path cannot be quoted unambiguously.

A Windows file name cannot contain ", and one ending in \ would escape the closing quote of its own quote pair.

Trait Implementations

impl Clone for CmdLineError

fn clone(&self) -> CmdLineError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CmdLineError

impl Eq for CmdLineError

impl Error for CmdLineError

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 From<CmdLineError> for LaunchError

fn from(source: CmdLineError) -> Self

Converts to this type from the input type.

impl PartialEq for CmdLineError

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

Equality operator ==.

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

Inequality operator !=.
