Function version_check::is_min_version [−][src]
pub fn is_min_version(min_version: &str) -> Option<(bool, String)>
Checks that the running or installed rustc
is at least some minimum
version.
The format of min_version
is a semantic version: 1.3.0
, 1.15.0-beta
,
1.14.0
, 1.16.0-nightly
, etc.
If the version cannot be retrieved or parsed, or if min_version
could not
be parsed, returns None
. Otherwise returns a tuple where the first value
is true
if the installed rustc
is at least min_version
and the second
value is the version (semantic) of the installed rustc
.
