Struct UnknownStability 

pub struct UnknownStability;

StabilityFloor::from_str’s error.

raw was not one of the five recognized stability keywords (dev, alpha, beta, rc, stable), matched ASCII-case-insensitively and with no surrounding-whitespace tolerance.

Examples

use deps_core::selection::{StabilityFloor, UnknownStability};

assert_eq!("betta".parse::<StabilityFloor>(), Err(UnknownStability));
assert_eq!(" beta".parse::<StabilityFloor>(), Err(UnknownStability));
