Function plugy_core::guest::read_msg

pub unsafe fn read_msg<T: DeserializeOwned>(value: u64) -> T

Deserializes a value using bincode from a combined representation.

This function takes a combined representation obtained from the write_msg function, which includes a pointer and length of a serialized buffer. The function safely deserializes the buffer back into a value implementing the serde::de::DeserializeOwned trait and returns it. The ownership of the buffer is transferred to the function, which takes care of proper deallocation.

Arguments

• value - The combined representation of the serialized buffer’s pointer and length, obtained from the write_msg function.

Returns

The deserialized value of type T.

Safety

This function is marked as unsafe because it involves working with raw pointers and memory management. The provided value parameter must be a valid combined representation obtained from the write_msg function, and incorrect usage can lead to memory corruption or other issues.

Examples

use plugy_core::guest::read_msg;
#[derive(serde::Deserialize)]
struct MyStruct {
    // Fields of MyStruct...
}

let combined: u64 = 0;/* ptr on the host side */;
let my_instance: MyStruct = unsafe { read_msg(combined) };
