Rust Crates for Time-Series Programming

Here’s a carefully selected list of high-quality Rust crates useful for time-series data processing, especially when dealing with stock prices, signals, or sequential datasets:


High-Quality Rust Crates for Time-Series Programming

1. polars

Critical Note: If you want "pandas-like" functionality for time-series, polars is the best Rust option right now.


2. chrono

Usage: Pair chrono with your data processing crates to manage time indices.


3. time-series

Critical Note: Not as mature as polars but lightweight and focused purely on time-series operations.


4. ta (Technical Analysis)

Usage: Essential for feature engineering in stock price prediction systems.


5. ndarray

Critical Note: Not time-series aware by itself, but perfect for raw numeric signal processing tasks.


Bonus Specialized Crates

CratePurpose
resampleAlgorithms for signal resampling (for irregular time-series).
interpolateInterpolation utilities for filling missing time-series data points.
statrsStatistical functions (mean, variance, probability distributions).

Recommended Stack for a Serious Time-Series Project


Critical Warning

Rust’s ecosystem for deep time-series modeling (like TensorFlow/Keras) is still emerging.
Crates like polars and ta are excellent for preprocessing.
For neural networks (especially LSTM), you may need to interoperate with Python frameworks like PyTorch or use FFI bindings.
