Struct wapc::ModuleState

source ·
pub struct ModuleState { /* private fields */ }
Expand description

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

Implementations§

source§

impl ModuleState

source

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

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

source

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

Retrieves the value of the current host response

source

pub fn set_guest_error(&self, error: String)

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

source

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

Sets the value indicating the response data from a guest call

source

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

Queries the value of the current guest response

source

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

Queries the value of the current host error

source

pub fn do_host_call( &self, binding: &str, namespace: &str, operation: &str, payload: &[u8] ) -> Result<i32, Box<dyn Error>>

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

source

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