Trait ContainerElement 

pub unsafe trait ContainerElement: Sized {
    const BUF_SIZE: u32;
    const RAW_COPYABLE: bool = false;

    // Required methods
    unsafe fn read_from_buf(buf: *const u8, written: u32) -> Self;
    unsafe fn write_to_buf(&self, buf: *mut u8) -> u32;
}

Trait for types that can be stored in UE containers.

Safety

BUF_SIZE must match what the C++ side expects for this element type. read_from_buf must correctly interpret the bytes written by C++’s ReadElement, and write_to_buf must produce bytes that C++’s WriteElement can interpret.

Required Associated Constants

const BUF_SIZE: u32

Buffer size for FFI transport. Must be large enough for the C++ side to write the element value.

Provided Associated Constants

const RAW_COPYABLE: bool = false

Whether this type can be bulk-copied as raw bytes (no per-element framing). True for fixed-size primitives (bool, integers, floats) and FName.

Required Methods

unsafe fn read_from_buf(buf: *const u8, written: u32) -> Self

Interpret bytes from the C++ side into a Rust value.

Safety

buf must point to at least written valid bytes produced by C++ ReadElement.

unsafe fn write_to_buf(&self, buf: *mut u8) -> u32

Write this value into a buffer for C++ WriteElement to consume. Returns the number of bytes written.

Safety

buf must point to at least BUF_SIZE writable bytes.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
