Struct abstutil::CmdArgs

pub struct CmdArgs {
    kv: HashMap<String, String>,
    bits: HashSet<String>,
    free: Vec<String>,
    used: HashSet<String>,
}

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

pub fn new() -> CmdArgs

On native, initialize with real flags. On web, transform URL query parameters into flags.

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.

pub fn from_args(raw: Vec<String>) -> CmdArgs

pub fn required(&mut self, key: &str) -> String

pub fn optional(&mut self, key: &str) -> Option<String>

pub fn optional_parse<T, E, F: Fn(&str) -> Result<T, E>>(
    &mut self,
    key: &str,
    parser: F
) -> Option<T>

pub fn true_false(&mut self, key: &str) -> bool

pub fn enabled(&mut self, key: &str) -> bool

pub fn required_free(&mut self) -> String

pub fn optional_free(&mut self) -> Option<String>

pub fn done(&mut self)
