Struct sunrise_fs::ipc::File

pub struct File {
    inner: Arc<Mutex<Box<dyn FileOperations>>>,
}

Represent a file in the IPC.

Fields

inner: Arc<Mutex<Box<dyn FileOperations>>>

The detail implementation of this ipc interface.

Implementations

impl File

pub fn new(inner: Box<dyn FileOperations>) -> Self

Create a new IFile instance from it's detail.

Trait Implementations

impl Clone for File

fn clone(&self) -> File

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for File

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

Formats the value using the given formatter.

impl IFile for File

fn read(
    &mut self,
    _manager: WorkQueue<'static>,
    _unknown_0: u32,
    offset: u64,
    length: u64,
    out_buffer: &mut [u8]
) -> Result<u64, Error>

Read the content of a file at a given offset in out_buf. option should be set to 0.

fn write(
    &mut self,
    _manager: WorkQueue<'static>,
    _unknown_0: u32,
    offset: u64,
    length: u64,
    in_buffer: &[u8]
) -> Result<(), Error>

Write the content given in_buf at the given offset in the file. If the file is too small to hold the data and the appendable flag is set, it will resize the file and append the data. If the file is too small to hold the data and the appendable flag isn't set, this will return a FileSystemError::NoSpaceLeft. option should be set to 0.

fn flush(&mut self, _manager: WorkQueue<'static>) -> Result<(), Error>

Flush any data not written on the filesystem.

fn set_size(
    &mut self,
    _manager: WorkQueue<'static>,
    new_size: u64
) -> Result<(), Error>

Resize the file with the given size. If the file isn't open with the appendable flag, it will not be extendable and will return a FileSystemError::NoSpaceLeft.

fn get_size(&mut self, _manager: WorkQueue<'static>) -> Result<u64, Error>

Return the current file size.

fn dispatch(
    &'a mut self,
    manager: WorkQueue<'static>,
    cmdid: u32,
    buf: &'a mut [u8]
) -> FutureObj<'a, Result<(), Error>>

Handle an incoming IPC request.
