Struct conrod::widget::id::Generator[][src]

pub struct Generator<'a> { /* fields omitted */ }

Used for generating new unique widget::Ids.

Generator is used by the widget_ids! macro and the types and fields that it generates in order to generate unique widget::Ids for each of the generated fields.


impl<'a> Generator<'a>

Constructor for a new widget::Id generator.

Generate a new, unique widget::Id into a Placeholder node within the widget graph. This should only be called once for each unique widget needed to avoid unnecessary bloat within the Ui's widget graph.

When using this method, be sure to store the returned widget::Id somewhere so that it can be re-used on next update.

Panics if adding another node would exceed the maximum capacity for node indices.
