Struct VertexAddr 

pub struct VertexAddr(/* private fields */);

The address of a vertex: a grid position or a symbol identity, in 8 bytes.

Implementations

impl VertexAddr

pub const INVALID: Self

The invalid sentinel. Neither a grid position nor a symbol.

pub fn grid(addr: GridAddr) -> Self

Address of a vertex that occupies a grid position.

pub const fn symbol(addr: SymbolAddr) -> Self

Address of a vertex identified by name rather than position.

pub fn as_grid(self) -> Option<GridAddr>

The grid position, or None for a symbol (or the invalid sentinel).

This is the only route from a stored vertex address to a (row, col), which is what keeps symbols out of grid-keyed structures.

pub fn as_symbol(self) -> Option<SymbolAddr>

The symbol identity, or None for a grid position.

pub fn is_symbol(self) -> bool

pub fn is_grid(self) -> bool

pub const fn as_u64(self) -> u64

pub fn order_key(self) -> (u32, u32)

Total order used to keep edge lists deterministic.

Grid vertices order by (row, col) exactly as they did when the arrays held bare coordinates. Symbols have no position, so they sort after every grid vertex, by allocation index.
