Implementations

impl<'s> UnparsedItem<'s>

pub fn keyword(&self) -> KeywordRef<'s>

Method returning copy of UnparsedItem::keyword field. The item’s Keyword

pub fn object(&self) -> Option<UnparsedObject<'s>>

Method cloning UnparsedItem::object field. The Item’s Object, if there was one

impl<'s> UnparsedItem<'s>

pub fn args_mut(&mut self) -> &mut ArgumentStream<'s>

Access the arguments, mutably (for consuming and parsing them)

pub fn args_copy(&self) -> ArgumentStream<'s>

Access a copy of the arguments

When using this, be careful not to process any arguments twice.

pub fn args(&self) -> &ArgumentStream<'s>

Access the arguments (readonly)

When using this, be careful not to process any arguments twice.

pub fn check_no_object(&self) -> Result<(), EP>

Check that this item has no Object.

pub fn invalid_argument_handler<E>( &self, field: &'static str, ) -> impl FnOnce(E) -> ErrorProblem

Convenience method for handling an error parsing an arguemnt

Returns a closure that converts every error into ArgumentError::Invalid and then to an ErrorProblem using .args().handle_error().

Useful in manual ItemValueParseable impls, when parsing arguments ad-hoc.
