Struct Link

pub struct Link { /* private fields */ }

Expand description

A link to the collector.

Functions passed to retire are called with a type-erased Link pointer. To extract the underlying value from a link, you can call the cast method.

Implementations§

impl Link

pub fn cast<T: AsLink>(link: mut Link) -> mut T

Cast this link to it’s underlying type.

Note that while this function is safe, using the returned pointer is only sound if the link is in fact a type-erased T. This means that when casting a link in a reclaimer, the value that was retired must be of type T.
