Struct ul::jsc::JSContextGroup

pub struct JSContextGroup {
    pub raw: JSContextGroupRef,
}

A group that associates JavaScript contexts with one another.

Contexts in the same group may share and exchange JavaScript objects. Sharing and/or exchanging JavaScript objects between contexts in different groups will produce undefined behavior. When objects from the same context group are used in multiple threads, explicit synchronization is required.
