Struct MaterialTable 

pub struct MaterialTable { /* private fields */ }

A 256-entry palette of Materials indexed by a per-voxel u8 material id. The renderer owns one table (a global palette); voxels reference materials by id rather than embedding them.

Id 0 is permanently Material::OPAQUE and cannot be redefined — it is the value every material-free voxel resolves to, so the opaque world stays byte-for-byte unchanged. set silently ignores id 0.

Implementations

impl MaterialTable

pub fn new() -> Self

A fresh palette: every id is Material::OPAQUE.

pub fn set(&mut self, id: u8, mat: Material) -> bool

Define material id. Id 0 is reserved as Material::OPAQUE and cannot be overwritten — defining it is a no-op that returns false; any other id returns true.

pub fn get(&self, id: u8) -> Material

The material at id (Material::OPAQUE for any never-set id).

pub fn all_opaque(&self) -> bool

True when every id is BlendMode::Opaque — lets a backend skip the whole transparency path while nothing translucent is defined.

pub fn as_array(&self) -> &[Material; 256]

The backing 256-entry array, for backends that upload it wholesale.

impl Default for MaterialTable

fn default() -> Self
