Enum CapSecError 

#[non_exhaustive]
pub enum CapSecError {
    OutOfScope {
        target: String,
        scope: String,
    },
    Io(Error),
    Revoked,
    Expired,
}

Errors that can occur when using capsec capabilities.

Most commonly seen when an Attenuated capability rejects an operation that falls outside its scope.

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.

OutOfScope

The target of a capability operation is outside the granted scope.

For example, trying to read /etc/passwd with a DirScope restricted to /tmp.

Fields

target: String

The path or address that was rejected.

scope: String

Description of the allowed scope.

Io(Error)

An I/O error from the underlying std operation.

Revoked

The capability was revoked via its associated Revoker.

Expired

The capability has expired (TTL elapsed).

Trait Implementations

impl Debug for CapSecError

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

Formats the value using the given formatter.

impl Display for CapSecError

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

Formats the value using the given formatter.

impl Error for CapSecError

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<Error> for CapSecError

fn from(source: Error) -> Self

Converts to this type from the input type.
