Struct ParsedArgs 

pub struct ParsedArgs<'a, const CAPACITY: usize = 1> { /* 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, const CAPACITY: usize> ParsedArgs<'a, CAPACITY>

pub fn parse_from(argv: &'a [&'a str], ids: &ArgLookupTable<'static>) -> Self

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

pub fn try_parse_from( argv: &'a [&'a str], table: &ArgLookupTable<'static>, ) -> Result<Self, Error>

Try to parse the input arguments.

pub fn contains(&self, id: &str) -> bool

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

pub fn get_one<T>(&self, id: &str) -> Option<Option<T>>

where T: FromStr,

Get one value for the given flag identifier.

pub fn get_many<B, T>(&self, id: &str) -> Option<B>

where B: FromIterator<T>, T: FromStr,

Get many values for the given flag identifier.

pub fn try_get_one<T>(&self, id: &str) -> Result<Option<Option<T>>, Error>

where T: FromStr,

Try to get and parse the argument value if any.

pub fn try_get_many<B, T>(&self, id: &str) -> Result<Option<B>, Error>

where B: FromIterator<T>, T: FromStr,

Try to get and parse the argument value if any. The value can be constructed from an iterator.
