Struct ModuleStateAsync 

pub struct ModuleStateAsync { /* private fields */ }

Available on crate feature async only.

Module state is essentially a ‘handle’ that is passed to a runtime engine to allow it to read and write relevant data as different low-level functions are executed during a waPC conversation

This version of ModuleState is designed for use in async contexts

Implementations

impl ModuleStateAsync

pub async fn get_guest_request(&self) -> Option<Invocation>

Retrieves the value, if any, of the current guest request

pub async fn get_host_response(&self) -> Option<Vec<u8>>

Retrieves the value of the current host response

pub async fn set_guest_error(&self, error: String)

Sets a value indicating that an error occurred inside the execution of a guest call

pub async fn set_guest_response(&self, response: Vec<u8>)

Sets the value indicating the response data from a guest call

pub async fn get_guest_response(&self) -> Option<Vec<u8>>

Queries the value of the current guest response

pub async fn get_host_error(&self) -> Option<String>

Queries the value of the current host error

pub async fn do_host_call( &self, binding: String, namespace: String, operation: String, payload: Vec<u8>, ) -> Result<i32, Box<dyn Error>>

Invoked when the guest module wishes to make a call on the host

pub fn do_console_log(&self, msg: &str)

Invoked when the guest module wants to write a message to the host’s stdout
