Struct RustyDataContainer 

pub struct RustyDataContainer { /* private fields */ }

A data container for communication with a C ABI.

The basic task of this container is to provide a C ABI compatible type to store arbitrary data arrays, and to convert them back and forth into corresponding Rust types.

Implementations

impl RustyDataContainer

pub fn from_slice<T: ConversionType>(slice: &[T]) -> Self

Create a new non-owning and non-mutable container from a given slice.

pub fn from_slice_mut<T: ConversionType>(slice: &mut [T]) -> Self

Create a new non-owning but mutable container from a given slice.

pub fn to_box(self) -> Box<RustyDataContainer>

pub unsafe fn to_vec<T: ConversionType>(self) -> Vec<T>

pub fn leak_mut( ptr: Option<Box<RustyDataContainer>>, ) -> &'static mut RustyDataContainer

Get a mutable reference to a RustyDataContainer from a ptr. Ensures that the destructor of the data container is not run.

pub fn leak(ptr: Option<Box<RustyDataContainer>>) -> &'static RustyDataContainer

Get a reference to a RustyDataContainer from a ptr. Ensures that the destructor of the data container is not run.

pub fn from_vec<T: ConversionType>(vec: Vec<T>) -> Self

Create a new owning and mutable container from a vector. The vector is consumed by this method.

pub unsafe fn as_slice<T: ConversionType>( ptr: Option<Box<RustyDataContainer>>, ) -> &'static [T]

Get a representation of the data as slice. This method does not take ownership of the container associated with ptr.

pub unsafe fn as_slice_mut<T: ConversionType>( ptr: Option<Box<RustyDataContainer>>, ) -> &'static mut [T]

Get a representation of the data as mutable slice. This method does not take ownership of the container associated with ptr.

Trait Implementations

impl Drop for RustyDataContainer

fn drop(&mut self)

Destroy a data container. If the container owns the data the corresponding memory is also deallocated.
