Struct sarge::ArgumentRef

pub struct ArgumentRef<T: ArgumentType> { /* private fields */ }

An internal tag to an argument. Use this to retrieve the value of an argument from an Arguments.

Implementations

impl<T: ArgumentType> ArgumentRef<T>

pub fn get(&self, args: &Arguments) -> ArgResult<T>

Retrieve the value of the argument from an Arguments.

Errors

If the argument type fails to parse, this will return that argument types error. If there was no value given to the argument, returns None.

For String and bool, this can never fail.

Trait Implementations

impl<T: Clone + ArgumentType> Clone for ArgumentRef<T>

fn clone(&self) -> ArgumentRef<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + ArgumentType> Debug for ArgumentRef<T>

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

Formats the value using the given formatter.

impl<T: PartialEq + ArgumentType> PartialEq for ArgumentRef<T>

fn eq(&self, other: &ArgumentRef<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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