version: 0.1.0
requirements:
ndk:
version: 26.0.0
rust:
stable:
version: 1.77.2

Example native_manifest.yaml file if project only requires NDK:
version: 0.1.0
requirements:
ndk:
version: 26.0.0

Example native_manifest.yaml file if project only requires both stable and nightly Rust and NDK:
version: 0.1.0
requirements:
