Enum DualFrontierError 

pub enum DualFrontierError {
    InvalidShape,
    NonCanonicalAbsence,
    ZeroSequence,
}

A safe failure to decode a canonical DualFrontier.

Variants

InvalidShape

A presence tag is not one of the two closed values.

NonCanonicalAbsence

A component is tagged absent but carries nonzero bytes.

ZeroSequence

A component is tagged present but encodes sequence zero.

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
