Struct PassedFlags 

pub struct PassedFlags {
    pub map: HashMap<String, String>,
}

Resolved flags delivered to the app’s main entry handler.

Constructed by crate::App::run when no subcommand is present and a main entry point has been registered via crate::App::main. The inner map uses canonical flag names as keys; boolean flags have the value "true".

Fields

map: HashMap<String, String>

The raw resolved flag map. Prefer the accessor methods over direct access.

Implementations

impl PassedFlags

pub fn get_flag_value(&self, name: &str) -> Option<&String>

Returns the value of a flag by its canonical name, if present.

Boolean flags (those with no explicit value) return "true".

pub fn contains_flag(&self, name: &str) -> bool

Returns true if the named flag was passed by the user.

Examples found in repository

examples/taskr.rs (line 138)

fn entry(flags: PassedFlags) {
    // Demonstrates: app-level main entry point with PassedFlags
    if flags.contains_flag("verbose") {
        println!("taskr: verbose mode active.");
    } else {
        println!("taskr: a toy task manager. Try 'taskr --help'.");
    }
}

pub fn iter(&self) -> impl Iterator<Item = (&String, &String)>

Iterates over all (name, value) pairs in the resolved flag map.
