Enum solana_libra_invalid_mutations::bounds::PointerKind

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

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.

Methods

impl PointerKind

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.

pub fn to_index_kind(self) -> IndexKind
