Struct enso_prelude::Immutable[−][src]

pub struct Immutable<T> { /* fields omitted */ }
Expand description

A zero-overhead newtype which provides immutable access to its content. Of course this does not apply to internal mutability of the wrapped data. A good use case of this structure is when you want to pass an ownership to a structure, allow access all its public fields, but do not allow their modification.
