#[repr(C, align(16))]pub struct VMContext {}Expand description
The VM “context”, which is pointed to by the vmctx arg in the compiler.
This has information about globals, memories, tables, and other runtime
state associated with the current instance.
The struct here is empty, as the sizes of these fields are dynamic, and we can’t describe them in Rust’s type system. Sufficient memory is allocated at runtime.
TODO: We could move the globals into the vmctx allocation too.
Implementations§
source§impl VMContext
impl VMContext
sourcepub(crate) unsafe fn instance(&self) -> &Instance
pub(crate) unsafe fn instance(&self) -> &Instance
Return a mutable reference to the associated Instance.
§Safety
This is unsafe because it doesn’t work on just any VMContext, it must
be a VMContext allocated as part of an Instance.
pub(crate) unsafe fn instance_mut(&mut self) -> &mut Instance
