Struct EnvParam 

pub struct EnvParam {
    pub owner: ObjectId,
    pub param: ObjectId,
}

One hidden parameter of a lifted GNU nested function.

GCC gives a nested function a static chain — a pointer to the enclosing frame — and writes a trampoline when its address is taken. This crate lambda-lifts instead: each enclosing object the body uses becomes a pointer parameter of its own, the body reads and writes it through that pointer, and every call site passes the address of the object it has. The sharing C promises is therefore kept — a store in the nested function is visible in the enclosing one — without a trampoline, at the price of not being able to hand the function’s address out.

Fields

owner: ObjectId

The enclosing function’s object the pointer carries.

param: ObjectId

The *mut T (or *const T) parameter of this function that holds its address.
