sourcepub fn get_variable<'a>(&self, key: &'a str) -> Option<&'a str>
pub fn get_variable<'a>(&self, key: &'a str) -> Option<&'a str>
Interface to acquire user-defined information from environment that cannot feasibly be supported in a multi-system way.
The key should be set to a key which has already been set by
set_variables or set_core_options.
Returns None if the variable could not be found.
