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.

InvalidName

A caller-supplied scope name was empty or not one safe path component.

Fields

name: String

Rejected scope name.

Timestamp

The host UTC clock could not be formatted for the scope identity.

Fields

source: Format

Timestamp-formatting failure.

Io

A filesystem operation failed at a scope boundary.

Fields

operation: &'static str

Stable filesystem action.

path: PathBuf

Affected root or scope path.

source: Error

Underlying operating-system failure.

IdentityExhausted

Generated identity attempts repeatedly collided with existing scopes.

Fields

root: PathBuf

Parent directory in which allocation was attempted.

Trait Implementations

impl Debug for ExecutionScopeError

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

Formats the value using the given formatter.

impl Display for ExecutionScopeError

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

Formats the value using the given formatter.

impl Error for ExecutionScopeError

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.
