# [−][src]Struct std::alloc::CannotReallocInPlace

    pub struct CannotReallocInPlace;

🔬 This is a nightly-only experimental API. (`allocator_api` #32838)

The `CannotReallocInPlace` error is used when `grow_in_place` or `shrink_in_place` were unable to reuse the given memory block for a requested layout.
