Expand description

Relative position of the access

Variants§

§

This

The accessed pointer is the current one

§

StrictChildAccess

The accessed pointer is a (transitive) child of the current one.

§

AncestorAccess

The accessed pointer is a (transitive) parent of the current one.

§

DistantAccess

The accessed pointer is neither of the above.

Implementations§

source§

impl AccessRelatedness

source

pub fn is_foreign(self) -> bool

Check that access is either Ancestor or Distant, i.e. not a transitive child (initial pointer included).

source

pub fn for_child(self) -> Self

Given the AccessRelatedness for the parent node, compute the AccessRelatedness for the child node. This function assumes that we propagate away from the initial access.
