impl ArgsParser for ClapArgsParser

fn parse(&self, args: impl IntoIterator<Item = OsString>) -> Args

Parses given cli args and perform basic error handling.

• If the underlying ProgramExit contains a ProgramExit::styled_message, it will be printed instead of ProgramExit::message.
• Will exit using ProgramExit::exit_status if any ProgramExit received.
• Will print to stderr on error, to stdout on early exit (i.e. version, author, help options)

See ArgsParser::parse for more infos.

fn try_parse( &self, args: impl IntoIterator<Item = OsString>, ) -> Result<Args, ProgramExit>

Parses given cli args and return them as an Args instance if no error or early exit occurred.
