Struct Argv

pub struct Argv {
    pub commands: Vec<String>,
    pub flags: HashMap<String, String>,
    /* private fields */
}

Example structure:

Argv {
  commands: Vec<String> [
     "command",
     "subcommand",
   ],
   flags: HashMap<String, String> {
     "test": "value",
     "production": "false",
     "help": "true",
     "try-me": "false",
   }
   after_double_dash: ""
}

Fields

commands: Vec<String>

Commands from argv

flags: HashMap<String, String>

Flags from argv in a key-value format

Implementations

impl Argv

Examples found in repository

examples/parser.rs (line 4)

fn main() {
  let args: Argv = Argv::parse();
  println!("{:#?}", args.commands);

  if args.commands.first().unwrap() == "hello" {
    println!("hello this is a command")
  }
}

Trait Implementations

impl Clone for Argv

fn clone(&self) -> Argv

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Argv

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Argv

fn default() -> Argv

Returns the “default value” for a type.

impl From<&[String]> for Argv

fn from(args: &[String]) -> Argv

Converts to this type from the input type.

impl From<&str> for Argv

fn from(args: &str) -> Argv

Converts to this type from the input type.

impl From<String> for Argv

fn from(args: String) -> Argv

Converts to this type from the input type.

impl PartialEq for Argv

fn eq(&self, other: &Argv) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
