Crate motion_core 

Backend-independent motion engine primitives.

This package owns time, geometry, animation, colors and diagnostics without rendering devices, font engines, media codecs or window-system dependencies.

use motion_core::{FrameRate, Time, TimeLiteral};
let boundary = Time::from_frame(30_000, FrameRate::NTSC);
assert_eq!(boundary, 1001.seconds().after_origin());
assert_eq!(boundary.to_frame(FrameRate::NTSC), 30_000);

Modules

animation

Clock-free easing and value interpolation.

asset

Lazy typed assets with explicit bounded project resource stores and request diagnostics.

audio

Stateless audio sources and immutable timeline occurrence metadata.

authoring

Immutable Node snapshots, scene evaluation and composition.

budget

Shared logical resource admission for bounded geometry and rendering.

color

Floating straight-alpha sRGB values and perceptual Oklab calculations.

display_list

Validated device-space drawing commands, with explicit transforms and resources.

drawing

Logical drawing contracts and bounded rectangle/path fill commands.

error

Unified engine failures with retained causes and frame diagnostics.

filter

Linear-light filter data, validation and conservative device bounds.

geometry

Double-precision authoring points, vectors, transforms and bounds.

grading

Immutable color grading data, without filesystem or renderer dependencies.

instances

Validated opaque instance records shared by content and render packages.

key

Bit-exact float keys for pure authoring caches.

math

Deterministic authoring mathematics and interpolation.

noise

Stateless integer-hashed procedural noise with analytic spatial derivatives.

optics

Bounded physical lens and height-field effect descriptions.

path2d

Double-precision path values, with copy-on-write geometry.

pixels

Immutable image sampling contracts, independent of decoding and rendering.

prelude

Backend-independent scene diagnostics and bounded structural traversal.

Macros

fps

Builds a FrameRate of whole frames per second from an integer constant.

group

Groups heterogeneous drawable or node values in source order.

Type Aliases

Result

A classified failure retaining its original source.
