pw_time

Robust time, instants, and durations for multiple clock domains

Experimental Rust

pw_time is a Rust Pigweed module that provides time types and clock domain facilities specifically tailored for embedded systems, with a strong focus on portability, correctness, and type safety.

The module allows type-safe handling of systems with multiple clock domains. Instants and durations are associated with a specific clock domain at compile-time, preventing developers from accidentally mixing times from different clocks.

API reference

Refer to the rustdoc API docs for detailed documentation of the pw_time Rust API.

Get started

To use pw_time, add it as a dependency in your BUILD.bazel file:

deps = [
    "//pw_time/rust:pw_time",
]

And import the types in your Rust source code:

use pw_time::{Clock, Instant, Duration};
