Struct GridBuilder 

pub struct GridBuilder { /* private fields */ }

Builder for applying validated bulk edits to a new Grid.

Implementations

impl GridBuilder

pub const fn new(width: usize, height: usize) -> GridBuilder

Queues edits for a width×height grid; dimensions are validated on Self::build.

Starts fully open with unit traversal costs. Call Self::index_reachability if the built grid should short-circuit disconnected start/goal pairs.

pub fn blocked<I, P>(self, points: I) -> GridBuilder

where I: IntoIterator<Item = P>, P: Into<Point>,

Marks all supplied cells as blocked.

pub fn open<I, P>(self, points: I) -> GridBuilder

where I: IntoIterator<Item = P>, P: Into<Point>,

Marks all supplied cells as open.

pub fn costs<I, P>(self, costs: I) -> GridBuilder

where I: IntoIterator<Item = (P, usize)>, P: Into<Point>,

Sets traversal costs from (point, cost) pairs.

pub const fn index_reachability(self) -> GridBuilder

Builds a reachability index after all edits have been applied.

pub fn build(self) -> Result<Grid, GridBuildError>

Builds the grid and validates every queued edit in insertion order.

Errors

Returns GridBuildError for invalid dimensions, allocation failure, or an invalid queued edit.
