version.TmuxVersion.require

require ( self , capability : &static str , needs : ReleaseVersion ) → Result<(), Error> method [source] ¶ method [source] ¶ require: Refuse a capability this release is too old for.

tmux usually accepts an unknown flag and ignores it, so without this "your tmux is too old" arrives as "the command did nothing". A development build carries no numbered release to compare and is taken at its word rather than refused.
Errors
Returns Error::UnsupportedCapability when this release is below needs.
