Enum WorkdirError 

pub enum WorkdirError {
    Refused(WorkdirRefusal),
    Io {
        path: String,
        source: Error,
    },
}

Error from a WorkdirRoot call.

Variants

Refused(WorkdirRefusal)

The call met a link or the wrong file type and did nothing. Already latched.

Io

The call failed for an ordinary I/O reason. path is in WorkdirRoot::display_path’s form, or the host path when a root opened by path could not be opened.

Fields

path: String

source: Error

Implementations

impl WorkdirError

pub fn is_not_found(&self) -> bool

Whether the call failed because the path does not exist.

Trait Implementations

impl Debug for WorkdirError

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

Formats the value using the given formatter.

impl Display for WorkdirError

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

Formats the value using the given formatter.

impl Error for WorkdirError

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<WorkdirError> for RuntimeError

A refusal is RuntimeError::WorkdirPathRefused; any I/O failure is RuntimeError::CreateWorkdir. Use RuntimeError::from_workdir where that variant is wrong.

fn from(error: WorkdirError) -> Self

Converts to this type from the input type.

impl From<WorkdirError> for Error

fn from(error: WorkdirError) -> Self

A refusal becomes PermissionDenied carrying the refusal’s text, for the callers whose own error type is io::Error. The refusal itself is already on the latch.
