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.

pub fn to_subset(&self) -> Option<SS>
pub fn to_subset(&self) -> Option<SS>
The inverse inclusion map: attempts to construct self
from the equivalent element of its
superset. Read more
pub fn is_in_subset(&self) -> bool
pub fn is_in_subset(&self) -> bool
Checks if self
is actually part of its subset T
(and can be converted to it).
pub fn to_subset_unchecked(&self) -> SS
pub fn to_subset_unchecked(&self) -> SS
Use with care! Same as self.to_subset
but without any property checks. Always succeeds.
pub fn from_subset(element: &SS) -> SP
pub fn from_subset(element: &SS) -> SP
The inclusion map: converts self
to the equivalent element of its superset.
