Struct Matches 

pub struct Matches { /* private fields */ }

Parse result containing matched arguments

Uses HashMap for O(1) argument lookups. Stores the active subcommand and all parsed argument values.

Implementations

impl Matches

pub fn subcommand(&self) -> Option<&str>

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

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

pub fn values(&self) -> &[String]

pub fn value_as<T>(&self, name: &str) -> Option<T>

where T: FromStr,

Get parsed value as specific type

Example

let port: u16 = matches.value_as("port").unwrap_or(8080);

pub fn any_present(&self, names: &[&str]) -> bool

Check if any of the given argument names is present

Example

if matches.any_present(&["verbose", "debug"]) {
    println!("Logging enabled");
}

pub fn all_present(&self, names: &[&str]) -> bool

Check if all of the given argument names are present

pub fn value_or<'a>(&'a self, name: &str, default: &'a str) -> &'a str

Get value or return a default

pub fn values_count(&self) -> usize

Get the number of positional arguments
