Struct ascesis::InContextMut

pub struct InContextMut<'a, D> where
    D: Contextual,  { /* fields omitted */ }

A short-term binding of Context and any mutable object of a type that implements the Contextual trait.

The purpose of this type is to allow a transparent read access to shared data, like names etc. To prevent coarse-grained locking, Context is internally represented by a ContextHandle; however, Context can't be modified through InContextMut.
