Struct Context 

pub struct Context<'a> { /* private fields */ }

Context wraps a single message request (and possibly response as well) along with the router callbacks necessary for making nested message calls.

Implementations

impl<'a> Context<'a>

pub fn new( context_info: ContextInfo, host_callbacks: &'a dyn HostBackend, ) -> Context<'a>

Create a new context from a message packet and host callbacks.

pub fn new_with_mem( context_info: ContextInfo, host_callbacks: &'a dyn HostBackend, mem: &'a MemoryManager, ) -> Context<'a>

Create a new context from a message packet and host callbacks with a pre-allocated memory manager.

pub fn self_account_id(&self) -> AccountID

This is the address of the account that is getting called. In a receiving account, this is the account’s own address.

pub fn caller(&self) -> AccountID

This is the address of the account which is making the message call.

pub unsafe fn host_backend(&self) -> &dyn HostBackend

Get the host backend.

pub fn memory_manager(&self) -> &MemoryManager

Get the memory manager.
