Module std::os::fortanix_sgx::usercalls::alloc

🔬 This is a nightly-only experimental API. (sgx_platform #56975)

Primitives for allocating memory in userspace as well as copying data to and from user memory.

Structs

Iter	Experimental Immutable user slice iterator
IterMut	Experimental Mutable user slice iterator
User	Experimental An owned type in userspace memory. User<T> is equivalent to Box<T> in enclave memory. Access to the memory is only allowed by copying to avoid TOCTTOU issues. The user memory will be freed when the value is dropped. After copying, code should make sure to completely check the value before use.
UserRef	Experimental A reference to some type in userspace memory. &UserRef<T> is equivalent to &T in enclave memory. Access to the memory is only allowed by copying to avoid TOCTTOU issues. After copying, code should make sure to completely check the value before use.

Traits

UserSafe	Experimental A type that can be represented in memory as one or more UserSafeSizeds.
UserSafeSized	Experimental A type that can be safely read from or written to userspace.
