Struct c_bridge::FfiObject

pub struct FfiObject { /* fields omitted */ }

A FFI object

Methods

impl FfiObject

pub const OPAQUE: u64

Indicates an opaque object

pub const DATA_ARRAY: u64

A byte array

pub const OBJECT_ARRAY: u64

An object array

pub const RUST_BOX: u64

An owned, boxed Rust object

pub const CUSTOM_MASK: u64

The mask for custom types

Warning: you have to ensure that you don't define the same value twice for different types. If you don't need to check against the type later, use OPAQUE.

pub fn release(&mut self)

Releases the payload if the struct is owned and sets it to unowned and empty in any case
