pub struct ScopeVec<T> { /* private fields */ }
Expand description
Small data structure to help extend the lifetime of a slice to a higher scope.
This is currently used during component translation where translation in
general works on a borrowed slice which contains all input modules, but
generated adapter modules for components don’t live within the original
slice but the data structures are much easier if the dynamically generated
adapter modules live for the same lifetime as the original input slice. To
solve this problem this ScopeVec
helper is used to move ownership of a
Vec<T>
to a higher scope in the program, then borrowing the slice from
that scope.
Implementations§
Source§impl<T> ScopeVec<T>
impl<T> ScopeVec<T>
Sourcepub fn push(&self, data: Vec<T>) -> &mut [T]
pub fn push(&self, data: Vec<T>) -> &mut [T]
Transfers ownership of data
into this scope and then yields the slice
back to the caller.
The original data will be deallocated when self
is dropped.
Sourcepub fn into_iter(self) -> impl ExactSizeIterator<Item = Box<[T]>>
pub fn into_iter(self) -> impl ExactSizeIterator<Item = Box<[T]>>
Iterate over items in this ScopeVec
, consuming ownership.
