Struct wasmtime_environ::ScopeVec

pub struct ScopeVec<T> { /* private fields */ }

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

impl<T> ScopeVec<T>

pub fn new() -> ScopeVec<T>

Creates a new blank scope.

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.
