Struct Cute

pub struct Cute<S: State> { /* private fields */ }

The main parser struct that holds options and their values.

Type Parameters

• S - The state type that implements the State trait

Implementations

impl<S: State> Cute<S>

pub fn new() -> Self

Creates a new Cute instance with empty options and values.

pub fn add(&mut self, arg: impl StateOpt<S = S> + 'static) -> &mut Self

Adds a new option to the parser.

Arguments

• arg - The option to add, must implement StateOpt

pub fn get(&self, s: S) -> Option<&dyn StateOpt<S = S>>

Gets an option by its state.

Arguments

• s - The state to search for

Returns

Option containing a reference to the option if found

pub fn has(&self, s: S) -> bool

pub fn value<V: ValueParser>(&self, s: S) -> Result<V::Out<'_>, V::Error>

Gets a parsed value for a given state.

Type Parameters

• V - The value parser type

Arguments

• s - The state to get the value for

Returns

Result containing the parsed value or an error

pub fn pop_raw_value(&mut self, s: S) -> Result<String, Error>

pub fn raw_values(&self, s: S) -> Result<&[String], Error>

pub fn parse<I: Iterator>(&mut self, iter: I) -> Result<Vec<String>, Error>

where I::Item: ToString,

Parses command-line arguments from an iterator.

Type Parameters

• I - The iterator type

Arguments

• iter - The iterator of arguments to parse

Returns

Result containing unprocessed arguments or an error

pub fn parse_env(&mut self) -> Result<Vec<String>, Error>

Parses arguments from the environment.

Returns

Result containing unprocessed arguments or an error

Trait Implementations

impl<S: Default + State> Default for Cute<S>

fn default() -> Cute<S>

Returns the “default value” for a type.
