Struct FFIBufManager

pub struct FFIBufManager { /* private fields */ }

Implementations

impl FFIBufManager

pub fn alloc(&mut self, len: FFIBufLen) -> FFIBufPtr

pub unsafe fn dealloc(&mut self, ptr: FFIBufPtr)

frees the memory pointed to by ptr

Safety

The pointer must have been allocated by FFIBufManager::alloc.

pub fn length(&self, ptr: FFIBufPtr) -> FFIBufLen

pub unsafe fn consume(&mut self, ptr: FFIBufPtr) -> FFIBuf

consumes the buffer pointed to by ptr and returns a Vec with the same contents.

Safety

The pointer must have been allocated by FFIBufManager::alloc.

pub fn encode<T: Serialize>(&mut self, data: &T) -> Result<FFIBufPtr, Error>

pub unsafe fn decode<T: DeserializeOwned>( &mut self, ptr: FFIBufPtr, ) -> Result<T, Error>

decode will consume the raw memory pointed to by ptr and return a deserialized object. After calling decode, manually deallocating the ptr is no longer needed.

Errors

This function will return an error if deserialization fails. If this happens the memory pointed to by the ptr will also be dropped.

Safety

The pointer must have been allocated by FFIBufManager::alloc.

impl Default for FFIBufManager

fn default() -> FFIBufManager
