Function version_check::is_min_date [−][src]
pub fn is_min_date(min_date: &str) -> Option<(bool, String)>
Checks that the running or installed rustc
was released no earlier than
some date.
The format of min_date
must be YYYY-MM-DD. For instance: 2016-12-20
or
2017-01-09
.
If the date cannot be retrieved or parsed, or if min_date
could not be
parsed, returns None
. Otherwise returns a tuple where the first value is
true
if the installed rustc
is at least from min_data
and the second
value is the date (in YYYY-MM-DD) of the installed rustc
.
