Method parse_subset

option_parser/src/lib.rs:172–174

Like [`parse`](Self::parse), but silently ignores unknown option names. This is useful when multiple parsers share the same input string and each only cares about a subset of the options.

(&mut self, input: &str)

    /// This is useful when multiple parsers share the same input string and
    /// each only cares about a subset of the options.
    pub fn parse_subset(&mut self, input: &str) -> OptionParserResult<()> {
        self.parse_inner(input, true)
    }

    /// Registers a named option that requires a value (i.e. `key=value`).
