Crate airbender_rt 

airbender-rt

Documentation: API docs | Guest program guide

[!WARNING] airbender-platform project is under active development and is in alpha state. Use at your own risk.

[!NOTE] Support crate. Most guest applications should depend on airbender-sdk instead, which re-exports the runtime, guest API, and codec helpers behind a single dependency.

airbender-rt is the low-level runtime support crate for Airbender guest programs. It handles bootstrapping, allocator setup, syscalls, and UART helpers used by the guest-facing APIs.

What It Provides

• start(...) and start_with_allocator_init(...) for guest bootstrapping.
• Built-in allocator backends for talc and bump allocation, plus hooks for custom allocators.
• Runtime modules for syscalls, UART output, and getrandom integration.
• Panic and allocation-error handlers for no_std riscv32 guest builds.

Features

• allocator-talc (default), allocator-bump, allocator-custom: select the runtime allocator model.
• std: enables the small amount of standard-library glue used by std guest builds.

Usage

Most guest applications should depend on airbender-sdk or airbender-guest. Depend on airbender-rt directly only when you need runtime-level control.
