pub enum PointerKind {
    One(IndexKind),
    Optional(IndexKind),
    Star(IndexKind),
}
Expand description

Represents the number of pointers that exist out from a node of a particular kind.

Variants§

§

One(IndexKind)

Exactly one pointer out with this index kind as its destination.

§

Optional(IndexKind)

Zero or one pointer out with this index kind as its destination. Like the ? operator in regular expressions.

§

Star(IndexKind)

Zero or more pointers out with this index kind as its destination. Like the * operator in regular expressions.

Implementations§

source§

impl PointerKind

source

pub fn pointers_from(src_kind: IndexKind) -> &'static [PointerKind]

A list of what pointers (indexes) exist out from a particular kind of node within the module.

The only special case is FunctionDefinition, which contains a CodeUnit that can contain one of several kinds of pointers out. That is not represented in this table.
