Struct enso_prelude::CowString [−][src]
pub struct CowString(_);
Expand description
A copy-on-write String implementation. It is a newtype wrapper for Cow<'static,str>
and
provides many useful impls for efficient workflow. Use it whenever you want to store a string
but you are not sure if the string will be allocated or not. This way you can store a static
slice as long as you can and switch to allocated String on demand.

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.
