Range corresponding to ((minX,maxX),(minY,maxY),...)

fn cmp_at(&self, other: &Self, level: usize) -> Ordering where
    Self: Sized, 

Compare elements at a level of tree depth. The dimension under consideration alternates each level, so you'll likely want the element at an index corresponding to level % dimension.

fn midpoint_upper(&self, other: &Self) -> Self where
    Self: Sized, 

For intervals, calculate the midpoint of the greater (upper) interval bound (ex: iv.1) for two intervals, returning a new interval where both elements are the midpoint result. For scalars, return the midpoint of two scalars as a scalar.

fn serialize_at(&self, level: usize, dst: &mut [u8]) -> Result<usize, Error>

Return the byte presentation for the element corresponding to the tree depth level for the purpose of making a pivot. If you have an interval type, return the upper bound.

fn dim() -> usize

Get the number of dimensions for this point type.

fn overlaps(&self, bbox: &Self::Bounds) -> bool

Return whether the current point intersects with a bounding box.

fn query_branch(
    buf: &[u8],
    bbox: &Self::Bounds,
    bf: usize,
    level: usize
) -> Result<(Vec<Cursor>, Vec<Block>), Error>

Return a set of (branch_offset,tree_depth) tuples (Cursors) for sub-branches to load next and a set of u64 (Blocks) to read data from according to a traversal of the branch data in buf at the tree depth level and subject to the bounds given in bbox.

fn pivot_bytes_at(&self, level: usize) -> usize

Return the size in bytes of the pivot-form of the element corresponding to the tree depth level.

fn count_bytes_at(buf: &[u8], level: usize) -> Result<usize, Error>

Calculate the number of bytes to read from buf for the tree depth level.

fn bounds(points: &Vec<Self>) -> Option<Self::Bounds>

Return a bounding box for a set of coordinates, if possible.

fn bounds_to_range(bbox: Self::Bounds) -> Self::Range

Return a Range corresponding to a bounding box. This involves transposing the items. For example:

fn format_at(_buf: &[u8], _level: usize) -> Result<String, Error>

Return a string representation of the element in a buffer slice corresponding to the tree depth level.
