Struct Config 

pub struct Config<'a> {
    pub levels: &'a [usize],
    pub lambdas: &'a [f32],
    pub is_geo: bool,
    pub max_cost: f32,
    pub window_size: i32,
    pub outer_window: i32,
    pub offsets: (usize, usize),
    pub window_mode: WindowMode,
    pub pa_to_pa: bool,
}

Settings of one connectivity call. Config::default() gives the Python defaults, with level 1 included as the core requires.

Fields

levels: &'a [usize]

Overview levels in base pixels per overview cell: powers of two forming a continuous sequence that includes 1, such as [1, 2, 4, 8, 16, 32], in any order.

lambdas: &'a [f32]

Dispersal kernel bandwidths in kilometres; the output is the mean of their scores. An empty slice scores every evaluated cell 0.

is_geo: bool

Whether transforms are geographic (degrees) rather than projected (metres).

max_cost: f32

Relative cost of crossing a fully degraded cell: a cell with traversal value t has path weight (1 - max_cost) * t + max_cost, so t = 1 costs 1 and t = 0 costs max_cost.

window_size: i32

Odd window size of every level but the coarsest. The level-L annulus spans L * window_size / 2 to L * window_size base pixels from the focal pixel centre, and level 1 is the disc of radius window_size; in square mode these are half-widths.

outer_window: i32

Odd window size of the coarsest level L, whose annulus reaches L * outer_window base pixels. Values below window_size use window_size.

offsets: (usize, usize)

Global (row0, col0) of the tile’s top-left pixel in the full raster, in base pixels; (0, 0) for a whole raster.

window_mode: WindowMode

Circular or square annuli.

pa_to_pa: bool

PARC target gating: only protected destinations, weighted by each overview cell’s protected fraction (unmasked share of its valid pixels), count in the connectedness numerator. Paths and the denominator are unchanged, and a focal cell that reaches no protected destination scores 0. For BERI it only makes focal cells without neighbours score 0; Python’s beri() never sets it.
