Module uniffi::ffi::rustbuffer
Structs
- Support for passing an allocated-by-Rust buffer of bytes over the FFI.
Functions
- This helper allocates a new byte buffer owned by the Rust code, and returns it to the foreign-language code as a
RustBuffer
struct. Callers must eventually free the resulting buffer, either by explicitly callinguniffi_rustbuffer_free
defined below, or by passing ownership of the buffer back into Rust code. - Free a byte buffer that had previously been passed to the foreign language code.
- This helper copies bytes owned by the foreign-language code into a new byte buffer owned by the Rust code, and returns it as a
RustBuffer
struct. Callers must eventually free the resulting buffer, either by explicitly calling the destructor defined below, or by passing ownership of the buffer back into Rust code. - Reserve additional capacity in a byte buffer that had previously been passed to the foreign language code.
