Enum EnvelopeMembershipError 

pub enum EnvelopeMembershipError {
    InexactEvidence,
    Unavailable,
    UnsupportedDerivation,
}

Why envelope membership could not be measured.

Variants

InexactEvidence

The evidence backing the measurement was not exact and reviewable.

Unavailable

The adapter cannot derive membership for the requested scope.

UnsupportedDerivation

The requested derivation is not supported by this source.

impl Eq for EnvelopeMembershipError

impl Error for EnvelopeMembershipError

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
