Fields

width: u32

height: u32

format: TexFormat

levels: Vec<Vec<u8>>

Mip levels, largest first; each exactly format.level_size(w >> i, h >> i) bytes (axes floor at 1).

color_space: ColorSpace

role: TexRole

normal: Option<NormalConvention>

For TexRole::Normal.

Trait Implementations

impl Clone for Texture

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 Texture

const VERSION: u32 = 3

3: the normal convention gained tangent/bitangent basis ordering.

fn payload_bytes(&self) -> u64

Every level’s bytes.

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

A size, at least one level and no more than the size has, each exactly its format’s size for its dimensions.

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

A summary, not the pixels: size, format, level count, colour space, role, normal convention.

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

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.

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 Texture

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

Formats the value using the given formatter.

impl PartialEq for Texture

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

Equality operator ==.

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

Inequality operator !=.
