Trait sp_runtime_interface::host::IntoPreallocatedFFIValue [−][src]
pub trait IntoPreallocatedFFIValue: RIType { type SelfInstance; fn into_preallocated_ffi_value(

allocated: Self::FFIType
) -> Result<()>; }
Expand description
Something that can be converted into a preallocated ffi value.
Every type parameter that should be given as &mut into a runtime interface function, needs
to implement this trait. After executing the host implementation of the runtime interface
function, the value is copied into the preallocated wasm memory.
This should only be used for types which have a fixed size, like slices. Other types like a vec do not work with this interface, as we can not call into wasm to reallocate memory. So, this trait should be implemented carefully.
Associated Types
type SelfInstance
type SelfInstanceAs Self can be an unsized type, it needs to be represented by a sized type at the host.
This SelfInstance is the sized type.
