⨍ Functions 136◇ Types & classes 21

↓ 13 callersMethodmassArray

Fast path for the renderer — one memcpy, no per-cell object churn.

src/js/lib/galaxy.ts:105

↓ 13 callersMethodtick

(&self, time: f32)

src/rust/galaxy.rs:222

↓ 12 callersMethodseed

Uniform random mass, zero initial velocity. Preserved for backwards-compatibility with the JS `Frontend.seed(mass)` call.

src/rust/galaxy.rs:92

↓ 9 callersMethodmass

Positions derivable from index + size. Kept for tests/older callers.

src/rust/galaxy.rs:283

↓ 7 callersMethodseed_with_mode

Seed with a named initial condition. Tuning constants assume default UI params (size=50, seed_mass=25).

src/rust/galaxy.rs:98

↓ 6 callersFunctionbench

(size: u16, ticks: u32, seed_mass: u16)

benches/tick_bench.rs:6

↓ 6 callersMethodseed_with

Reproducible [`seed`] variant. Same `(additional, seed)` gives byte-identical state, enabling `?seed=...` URL sharing.

src/rust/galaxy.rs:217

↓ 6 callersMethodtick_with_accel

Tick using externally-computed forces (e.g. WebGPU compute shader). Mismatched slice lengths default to zero-force.

↓ 1 callersMethodseedWith

Reproducible seed. BigInt so u64 seeds round-trip cleanly.

src/js/lib/galaxy.ts:70

↓ 1 callersMethodseed_with_rng

Shared seeding kernel. wasm-bindgen can't take generics, hence the split.

src/rust/galaxy.rs:347

Point renderer at worker-produced mass buffer. Skips WASM round-trip.

src/js/lib/galaxy.ts:163
