Function casperlabs_contract::ext_ffi::is_valid_uref

pub unsafe extern "C" fn is_valid_uref(
    uref_ptr: *const u8, 
    uref_size: usize
) -> i32

This function checks if all the keys contained in the given Value are valid in the current context (i.e. the Value does not contain any forged casperlabs_types::uref::URefs). This function causes a Trap if the bytes in wasm memory from offset value_ptr to value_ptr + value_size cannot be de-serialized as type Value.
