Struct ParsedArgs

pub struct ParsedArgs<'a, const ARG_COUNT_MAX: usize = 8> { /* private fields */ }

Defines the result of argument parsing. This is a simple key-value store that offers a look-up over parsed arguments.

Implementations

impl<'a> ParsedArgs<'a>

pub fn parse<I>(tokens: I) -> Self

where I: Iterator<Item = Token<'a>>,

Parse the command line input from a token stream. The result is the set of found arguments.

pub fn get<'k, T>(&self, key: &'k str) -> Result<Option<T>, Error>

where T: FromStr, 'a: 'k,

Try to get and parse the argument value if any.

pub fn is_enabled<'k>(&self, key: &'k str) -> bool

where 'a: 'k,

Check if there exists an argument with the given key (i.e. short or long flag).

Trait Implementations

impl<'a, const ARG_COUNT_MAX: usize> Debug for ParsedArgs<'a, ARG_COUNT_MAX>

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

Formats the value using the given formatter.

impl<'a, const ARG_COUNT_MAX: usize> Default for ParsedArgs<'a, ARG_COUNT_MAX>

fn default() -> ParsedArgs<'a, ARG_COUNT_MAX>

Returns the “default value” for a type.
