Function casper_contract::ext_ffi::new_uref

pub unsafe extern "C" fn new_uref(
    uref_ptr: *mut u8, 
    value_ptr: *const u8, 
    value_size: usize
)

This function causes the runtime to generate a new [casper_types::uref::URef], with the provided value stored under it in the global state. The new [casper_types::uref::URef] is written (in serialized form) to the wasm linear memory starting from the key_ptr offset. Note that data corruption is possible if not enough memory is allocated for the [casper_types::uref::URef] at key_ptr. This function will cause a Trap if the bytes in wasm memory from offset value_ptr to value_ptr + value_size cannot be de-serialized into a Value.

Arguments

• key_ptr - pointer to the offset in wasm memory where the new [casper_types::uref::URef] will be written
• value_ptr - pointer to bytes representing the value to write under the new [casper_types::uref::URef]
• value_size - size of the value (in bytes)
