Struct PathNode 

pub struct PathNode {
    pub i: usize,
    pub j: isize,
    pub is_snake: bool,
    pub is_bootstrap: bool,
    pub prev: Option<usize>,
}

Fields

i: usize

j: isize

is_snake: bool

is_bootstrap: bool

prev: Option<usize>

Implementations

impl PathNode

pub fn new( i: usize, j: isize, is_snake: bool, is_bootstrap: bool, prev: Option<usize>, ) -> Self

pub fn fmt_path(arena: &[PathNode], start_idx: usize) -> String

pub fn previous_snake(arena: &[PathNode], idx: usize) -> Option<usize>

Exact port of Java’s PathNode.previousSnake(): if (isBootstrap()) return null; if (!isSnake() && prev != null) return prev.previousSnake(); return this;

Called on a node (by index) the same way Java calls somePrev.previousSnake().
