Fields

shape: TextureShape

width: u32

height: u32

format: TexFormat

levels: Vec<Vec<Vec<u8>>>

levels[level][layer], largest level first; each layer exactly format.level_size(w >> level, h >> level) bytes (axes floor at 1) and each level TextureShape::layers_at layers.

color_space: ColorSpace

role: TexRole

normal: Option<NormalConvention>

For TexRole::Normal.

Implementations

impl TextureLayers

pub fn layer(&self, level: usize, layer: usize) -> Option<&[u8]>

The layer layer of level level.

Trait Implementations

impl Clone for TextureLayers

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Component for TextureLayers

fn payload_bytes(&self) -> u64

Every layer of every level.

fn verify(&self, _e: Entity, _w: &World) -> Result<(), String>

A size, a shape with something in it, at least one level and no more than the size has, each level the shape’s number of layers and each layer exactly its format’s size for the level’s dimensions.

fn to_json(&self) -> Result<Option<Value>, JsonError>

A summary, not the pixels.

const NAME: &'static str = "core.texture_layers"

const GEOMETRY: Geometry = crate::Geometry::None

What the value holds of its entity’s mesh primitives and vertices (Geometry). Stated by every component, with no default, so data that describes a mesh can’t be left behind by an edit of it unawares: the World’s edit paths take it from there.

const VERSION: u32 = 1

Schema version of the component’s content. Bump it when the meaning or layout of a field changes.

fn references(&self, _out: &mut Vec<Entity>)

The entities this component refers to (a prototype, materials, textures), appended to out: the edges World::closure follows. A component holding entity references must declare every one of them.

fn remap_primitives(&self, _from: &[usize]) -> Option<Result<Self, String>>

The component after its entity’s mesh primitives were rebuilt, for a component that holds something per primitive (Geometry::PerPrimitive, Geometry::PerVertex): new primitive i comes from old primitive from[i] (a source may repeat, when a primitive is split, or be absent, when one is dropped). Such a component always answers (a value holding nothing per primitive answers with itself); None, the default, is for components of Geometry::None, and World::remap_primitives refuses a dependent component that gives it. An index the component does not have is an error. remap_list does the work for a list with one entry per primitive.

fn remap_vertices( &self, _primitive: usize, _from: &[u32], ) -> Option<Result<Self, String>>

The component after the vertices of its entity’s mesh primitive primitive were compacted or reordered, for a component that holds something per vertex (Geometry::PerVertex): new vertex i of that primitive is old vertex from[i] (a source may repeat or be absent). Such a component always answers (with itself when it holds nothing for that primitive); None, the default, is for the others, and World::remap_vertices refuses a per-vertex component that gives it. An index the component does not have is an error. Every pass that compacts or reorders a primitive’s vertices calls World::remap_vertices. After a rebuild of the primitive list (World::rebuild_primitives, Component::remap_primitives) a primitive’s per-vertex data is its source primitive’s, and the vertex map is relative to that source.

fn blend_vertices( &self, _primitive: usize, _from: &[VertexBlend], ) -> Option<Result<Self, String>>

The component after the vertices of its entity’s mesh primitive primitive were rebuilt as blends of old ones (VertexBlend), for a component that holds something per vertex (Geometry::PerVertex): new vertex i is the combination from[i] of old vertices, in whatever way the component’s data combines (a morph target’s delta is interpolated, the way the surface it moves is). It answers as Component::remap_vertices does: with itself when it holds nothing for that primitive; None, the default, is for a component that does not know how to combine its data, and World::blend_vertices refuses a per-vertex component that gives it. An index the component does not have is an error. A vertex that is a copy of one old vertex (VertexBlend::copy) is the case Component::remap_vertices states, and a component answering one answers the other alike.

fn apply_linear(&self, _l: &Linear) -> Linearity<Self>

The component after its entity’s local space was mapped by l (a pass that bakes a placement’s mirror or shear into a copy of its geometry, so transforms stay rigid). World::apply_linear calls it for every component of the entity. The default is Linearity::Unsupported: a component that holds local-space geometry and does not say how it follows is never silently left behind; one without geometry says Linearity::Invariant.

fn restate(&self, _resolved: &Resolved<'_>) -> Restated<Self>

The component after resolve-state (crate::state::ResolveState) gave the axes in resolved their values: a component that holds crate::state::Clauses of its own (a record of parts each present in some states) reduces them as core.condition is reduced (crate::state::Resolved::reduce: a clause that fails is dropped, a clause left with no literal holds whatever the other axes are). Restated::Absent says the entity is not present in this state (every clause failed): it is despawned as one whose core.condition fails is. The default holds no clause: Restated::Unchanged.

impl Debug for TextureLayers

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for TextureLayers

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
