Struct Evaluation 

pub struct Evaluation { /* private fields */ }

Time, quality and explicit resources for one evaluation.

SceneContext and DrawContext build on the same environment so deferred content sees identical time, quality, assets, fonts, diagnostics and compute caches whichever one measures or records it. The environment is immutable once shared; builders take self and drawing contexts hold it by Arc.

Implementations

impl Evaluation

pub fn new() -> Self

Creates a Final-quality environment at time zero without assets or caches.

pub fn with_quality(self, quality: RenderQuality) -> Self

Selects an explicit approximation policy for deferred content.

pub fn quality(&self) -> RenderQuality

Production quality is the default.

pub fn with_time(self, time: Time) -> Self

Supplies scene-local signed time to deferred content effects.

pub fn time(&self) -> Time

Scene-local time; defaults to zero.

pub fn with_assets(self, assets: &Assets) -> Self

Captures the same lazy/preloaded owner used by the enclosing session.

The assets inherit this environment’s diagnostics, and their font environment replaces any previously supplied one.

pub fn assets(&self) -> &Assets

Explicit resource owner; an unconfigured environment resolves no relative files.

pub fn with_fonts(self, fonts: impl Into<FontEnvironment>) -> Self

Supplies a shared explicit font snapshot.

pub fn fonts(&self) -> Option<&FontEnvironment>

Font environment for paragraph text, optional for geometry-only content.

pub fn with_diagnostics(self, diagnostics: RequestDiagnostics) -> Self

Carries request diagnostics explicitly through deferred content compilation.

pub fn diagnostics(&self) -> &RequestDiagnostics

Request-owned sink; cloning the environment preserves its identity.

pub fn with_cache(self, cache: RenderCache) -> Self

Supplies partitioned compute caches shared by rendering workers.

pub fn cache(&self) -> Option<&RenderCache>

Shared compute-cache partitions, absent for standalone uncached evaluation.

pub fn shared(self) -> Arc<Self>

Shares this environment between contexts without copying it.

Trait Implementations

impl Clone for Evaluation

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Evaluation

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

Formats the value using the given formatter.

impl Default for Evaluation

fn default() -> Self

Returns the “default value” for a type.
