Struct HFILE

pub struct HFILE(/* private fields */);

Available on crate feature kernel only.

Handle to a file. Originally just a HANDLE.

Unless you need something specific, consider using the File high-level abstraction.

Trait Implementations

impl Debug for HFILE

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for HFILE

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Handle for HFILE

const NULL: Self

The null, uninitialized handle; equals to 0.

const INVALID: Self

The invalid handle; equals to -1.

unsafe fn from_ptr(p: *mut c_void) -> Self

Creates a new handle object by wrapping a pointer.

unsafe fn as_mut(&mut self) -> &mut *mut c_void

Returns a mutable reference to the underlying raw pointer.

unsafe fn raw_copy(&self) -> Self

Returns a raw copy of the underlying handle pointer.

fn ptr(&self) -> *mut c_void

Returns the underlying raw pointer.

fn as_opt(&self) -> Option<&Self>

Returns None if the handle is null or invalid, otherwise returns Some(&self).

impl Hash for HFILE

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl LowerHex for HFILE

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for HFILE

fn eq(&self, other: &HFILE) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl UpperHex for HFILE

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl kernel_Hfile for HFILE

SetFileTime function.

fn WriteFile(&self, data: &[u8]) -> SysResult<u32>

WriteFile function.
