Trait IndexableNum

pub trait IndexableNum:
    Sealed
    + Num
    + NumCast
    + PartialOrd
    + Debug
    + Send
    + Sync
    + Pod
    + Bounded {
    const TYPE_INDEX: u8;
    const BYTES_PER_ELEMENT: usize;
}

A trait for types that can be used for indexed coordinates.

This trait is sealed and cannot be implemented for external types. This is because we want to ensure FFI compatibility with other implementations, including the reference implementations in JavaScript (rtree, kdtree)

Required Associated Constants

const TYPE_INDEX: u8

The type index to match the array order of ARRAY_TYPES in flatbush JS

const BYTES_PER_ELEMENT: usize

The number of bytes per element

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
