pub fn parse_threshold_cli(
s: &str,
key_count: usize,
) -> Result<Threshold, Error>Expand description
Parse a threshold argument from the CLI.
Accepts either a plain integer ("2", "a" hex) for Threshold::Simple
or a comma-separated fraction list ("1/2,1/2,1/2") for
Threshold::Weighted. Rejects mixed shapes ("2,3" with no /) with
a clear error.
