Struct rdisk_shared::StructBuffer

pub struct StructBuffer<T: Sized> { /* fields omitted */ }

Methods

impl<T: Sized + Clone + Copy> StructBuffer<T>

pub unsafe fn new() -> Self

Creates a buffer capable to hold the value of type T.

Safety

The buffer is uninitialized!

pub unsafe fn with_ext(ext_size: usize) -> Self

Creates a buffer capable to hold the value of type T plus ext_size bytes.

Safety

The buffer is uninitialized!

pub unsafe fn with_buffer(buffer: Vec<u8>) -> Self

Creates a StructBuffer for the type T using supplied buffer.

Safety

The buffer size should be >= mem::size_of::() !

pub fn with_value(value: &T) -> Self

Creates a StructBuffer for the type T using supplied T value.

Safety

The buffer size should be >= mem::size_of::() !

pub fn zeroed() -> Self

Creates the value of type T represented by the all-zero byte-pattern.

Trait Implementations

impl<T: Sized + Clone + Copy> AsByteSlice for StructBuffer<T>

unsafe fn as_byte_slice(&self) -> &[u8]

Safety The method is unsafe because any padding bytes in the struct may be uninitialized memory (giving undefined behavior). Also, there are not any Endianness assumtions. The caller should care about it.

impl<T: Sized + Clone + Copy> AsByteSliceMut for StructBuffer<T>

unsafe fn as_byte_slice_mut(&mut self) -> &mut [u8]

Safety The method is unsafe because any padding bytes in the struct may be uninitialized memory (giving undefined behavior). Also, there are not any Endianness assumtions. The caller should care about it.

impl<T: Clone + Sized> Clone for StructBuffer<T>

fn clone(&self) -> StructBuffer<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Sized + Clone + Copy> Deref for StructBuffer<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T: Sized + Clone + Copy> DerefMut for StructBuffer<T>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.
