Struct RecType 

Source 
pub struct RecType {
    pub open: Cell<bool>,
    pub members: RefCell<Vec<Member>>,
    pub asserts: RefCell<Vec<AssertItem>>,
    pub ctx_decls: RefCell<Vec<(String, RT)>>,
    pub filling: Cell<bool>,
    pub pending: RefCell<Vec<(RT, RT)>>,
}
Expand description

a record type’s shape

Fields§

§open: Cell<bool>

whether it is open

§members: RefCell<Vec<Member>>

its members

§asserts: RefCell<Vec<AssertItem>>

its assertions and guarded groups

§ctx_decls: RefCell<Vec<(String, RT)>>

context $parent: ref<T> declarations (D30), checked at embedding sites

§filling: Cell<bool>

still being filled; extensions of it wait in pending (§3.14)

§pending: RefCell<Vec<(RT, RT)>>

extensions not yet merged (recursive types)
