Enum StabilityFloor 

pub enum StabilityFloor {
    Dev,
    Alpha,
    Beta,
    Rc,
    Stable,
}

A Composer minimum-stability floor (or per-dependency @stability flag), ranked Dev < Alpha < Beta < Rc < Stable (#424, #1444).

Declaration order is the precedence order: Ord compares two floors exactly as Composer’s own stability scale does, so StabilityFloor::Beta < StabilityFloor::Rc holds via the derived comparison, with no separate rank table to keep in sync.

This is the manifest-declared stability floor’s own type — strict, via FromStr — distinct from the lenient qualifier classification a version string’s own suffix (e.g. 1.0.0-beta.1) goes through inside deps-composer’s compare_versions, which still accepts the a/b short aliases and maps an unrecognized word to Self::Stable — that leniency is unchanged by this type.

Examples

use deps_core::selection::StabilityFloor;

assert!(StabilityFloor::Dev < StabilityFloor::Alpha);
assert!(StabilityFloor::Alpha < StabilityFloor::Beta);
assert!(StabilityFloor::Beta < StabilityFloor::Rc);
assert!(StabilityFloor::Rc < StabilityFloor::Stable);

Variants

Dev

dev — the loosest floor; admits every stability level.

Alpha

alpha.

Beta

beta.

Rc

RC (release candidate).

Stable

stable — the strictest floor; Composer’s own default.

Trait Implementations

impl Clone for StabilityFloor

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for StabilityFloor

impl Debug for StabilityFloor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for StabilityFloor

impl FromStr for StabilityFloor

fn from_str(s: &str) -> Result<Self, Self::Err>

Strict: accepts exactly dev, alpha, beta, rc, stable, ASCII-case-insensitively (so RC, Beta, STABLE still parse) — no surrounding whitespace tolerance, and no a/b short-alias acceptance (those are valid only inside a version qualifier suffix, not as a minimum-stability config value or @flag).

This is the strict, config-value classifier; deps-composer’s own qualifier_stability (private to that crate) is the deliberately separate, lenient classifier for a version string’s own qualifier suffix (accepts a/b, defaults an unrecognized word to StabilityFloor::Stable) — if a keyword is ever added here, check whether it belongs there too.

Examples

use deps_core::selection::StabilityFloor;

assert_eq!("beta".parse(), Ok(StabilityFloor::Beta));
assert_eq!("RC".parse(), Ok(StabilityFloor::Rc));
assert_eq!("STABLE".parse(), Ok(StabilityFloor::Stable));

assert!("a".parse::<StabilityFloor>().is_err());
assert!("b".parse::<StabilityFloor>().is_err());
assert!("".parse::<StabilityFloor>().is_err());
assert!(" beta".parse::<StabilityFloor>().is_err());
assert!("stable ".parse::<StabilityFloor>().is_err());

type Err = UnknownStability

The associated error which can be returned from parsing.

impl Hash for StabilityFloor

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Ord for StabilityFloor

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,
