Description#
Development identifiers meet only requirements at or below the crate's minimum supported release; they are not promoted to an invented release. A
next-X.Yidentifier's own release number is not read here even whenrequiredis that sameX.Yor earlier -- this is a floor check, not a capability check. Asking "does this tree already contain a capability that shipped at version V" isSelf::has_behavior()'s question, not this one; a call site gating a specific capability behind a release aboveSelf::MIN_SUPPORTEDalmost always wants that instead, or it refuses a development build that already has the capability it is checking for.Examples#
use libtmux::TmuxVersion;let version = TmuxVersion::parse_output(b"tmux 3.3a\n")?;assert!(version.meets(&TmuxVersion::MIN_SUPPORTED));The English verb suggests this answers "is a capability available", but on a development build it can refuse one that is already there:
use libtmux::{ReleaseSuffix, ReleaseVersion, TmuxVersion};let next = TmuxVersion::parse_output(b"tmux next-3.9\n")?;let capture_line_flags = ReleaseVersion::new(3, 7, ReleaseSuffix::FINAL);// `next-3.9`'s tree already has 3.7's behavior, but this clamps every// development identifier to the crate's floor, so it says no anyway.// `TmuxVersion::has_behavior` is the question that says yes.assert!(!next.meets(&capture_line_flags));assert!(next.has_behavior(&capture_line_flags));- Parameters
