[−][src]Struct abstutil::CmdArgs
Yet another barebones command-line flag parsing library.
Fields
kv: HashMap<String, String>
bits: HashSet<String>
free: Vec<String>
used: HashSet<String>
Implementations
impl CmdArgs
[src]
pub fn new() -> CmdArgs
[src]
On native, initialize with real flags. On web, always empty.
Calling this has the side-effect of initializing logging on both native and web. This should probably be done independently, but for the moment, every app wants both.
