Enum ScopeAccessError 

pub enum ScopeAccessError {
    ReadDenied {
        capability: &'static str,
    },
    WriteDenied {
        capability: &'static str,
    },
    CannotExitRoot,
}

Typed read/write boundary failures for scoped runtime state.

Variants

ReadDenied

Node attempted to read scope with an invalid capability.

Fields

capability: &'static str

Capability used for the read.

WriteDenied

Node attempted to write scope with an invalid capability.

Fields

capability: &'static str

Capability used for the write.

CannotExitRoot

Attempted to exit root scope.

Trait Implementations

impl Clone for ScopeAccessError

fn clone(&self) -> ScopeAccessError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScopeAccessError

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

Formats the value using the given formatter.

impl Display for ScopeAccessError

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

Formats the value using the given formatter.

impl Error for ScopeAccessError

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 ScopeAccessError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
