Function casperlabs_contract::ext_ffi::write_local

pub unsafe extern "C" fn write_local(
    key_ptr: *const u8, 
    key_size: usize, 
    value_ptr: *const u8, 
    value_size: usize
)

The bytes in wasm memory from offset key_ptr to key_ptr + key_size will be used together with the current context’s seed to form a local key. This function writes the provided value (read via de-serializing the bytes in wasm memory from offset value_ptr to value_ptr + value_size) under that local key in the global state. This function will cause a Trap if the value fails to de-serialize.

Arguments

• key_ptr - pointer to bytes representing the user-defined key to write to
• key_size - size of the key (in bytes)
• value_ptr - pointer to bytes representing the value to write at the key
• value_size - size of the value (in bytes)
