Poll a Rust future uniffi_rustbuffer_alloc Reexport items from other uniffi creates
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 calling uniffi_rustbuffer_free uniffi_rustbuffer_free Reexport items from other uniffi creates
Free a byte buffer that had previously been passed to the foreign language code. uniffi_rustbuffer_from_bytes Reexport items from other uniffi creates
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. uniffi_rustbuffer_reserve Reexport items from other uniffi creates
Reserve additional capacity in a byte buffer that had previously been passed to the
foreign language code. ForeignFutureCallback Reexport items from other uniffi creates
