Struct lunatic_runtime::api::process::ProcessEnvironment

pub struct ProcessEnvironment<T: Clone> { /* fields omitted */ }

This structure is captured inside HOST function closures passed to Wasmtime’s Linker. It allows us to expose Lunatic runtime functionalities inside host functions, like async yields or Instance memory access.

Safety

Having a mutable slice of Wasmtime’s memory is generally unsafe, but Lunatic always uses static memories and one memory per instance. This makes it somewhat safe?
