Implementations

impl ActionTarget<'_, '_>

pub fn is_this(&self) -> bool

Returns true if the action_target is [This].

pub fn from_name_and_fields<'a, 'b>(
    slice: &'a [&'b str]
) -> ActionTarget<'a, 'b>

Create an ActionTarget by stripping the first element off the given slice.

assert_eq!(ActionTarget::from_name_and_fields(["foo"]), ActionTarget::This);
assert_eq!(ActionTarget::from_name_and_fields(["foo", "bar"]), ActionTarget::Field(&["bar"]));

pub fn strip_one_field(&self) -> Option<(&str, ActionTarget<'_, '_>)>

If this is a ActionTarget::Field, return the topmost field name and the ActionTarget to use when calling the field. Otherwise, return None.

assert_eq!(ActionTarget::This.strip_one_field(), None);
assert_eq!(ActionTarget::Field(&["foo"]).strip_one_field(), Some(("foo", ActionTarget::This)));
assert_eq!(ActionTarget::Field(&["foo", "bar"]).strip_one_field(), Some(("foo", ActionTarget::Field(&["bar"]))));
