Enum ResolutionError 

pub enum ResolutionError {
    InvalidRequest,
    InvalidWorkingDirectory,
    InvalidSearchDirectory {
        index: usize,
    },
    NotFound,
    NotRegularFile,
    NotExecutable,
    Io {
        directory: Option<usize>,
        source: Error,
    },
}

Executable selection failed before any admission or execution.

Variants

InvalidRequest

The request is empty, contains NUL, or is a bare . or ...

InvalidWorkingDirectory

The working directory is relative or contains NUL.

InvalidSearchDirectory

A caller-supplied search directory contains NUL.

Fields

index: usize

Zero-based position in the caller’s search order.

NotFound

No regular file with Unix executable permission bits was found.

NotRegularFile

An explicitly requested path is not a regular file.

NotExecutable

An explicitly requested file has no Unix executable permission bits.

Io

Metadata or canonicalization failed. Search stops on errors other than missing candidates rather than silently selecting a later directory.

Fields

directory: Option<usize>

Search-directory position, or None for an explicitly requested path.

source: Error

Underlying filesystem failure, without rendered input paths.

Trait Implementations

impl Debug for ResolutionError

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

Formats the value using the given formatter.

impl Display for ResolutionError

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

Formats the value using the given formatter.

impl Error for ResolutionError

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.
