Enum WeightedQuorumSetError 

pub enum WeightedQuorumSetError<ID> {
    ZeroWeight {
        id: ID,
    },
    ZeroThreshold,
}

An error returned when building an invalid WeightedQuorumSet.

Both cases are caller bugs: an ID with weight 0 would never count, and a threshold of 0 would make the empty set a quorum. Construction reports them instead of repairing the input, so the mistake surfaces where it is made.

Variants

ZeroWeight

An ID has weight 0, so it would never count.

Fields

id: ID

The first ID with weight 0.

ZeroThreshold

The threshold is 0, so the empty set would be a quorum.

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
