1//! Defines the common arrays used to access bindless resources.
2//!
3//! This need to be kept up to date with the `BINDING_NUMBERS` table in
4//! `bindless.rs`.
5//!
6//! You access these by indexing into the bindless index table, and from there
7//! indexing into the appropriate binding array. For example, to access the base
8//! color texture of a `StandardMaterial` in bindless mode, write
9//! `bindless_textures_2d[materials[slot].base_color_texture]`, where
10//! `materials` is the bindless index table and `slot` is the index into that
11//! table (which can be found in the `Mesh`).
