pub fn size(&self) -> u64

pub fn truncate(&mut self)

pub fn read( &self, offset: u64, n: usize, result: *mut Slice, scratch: *mut u8, ) -> Status

pub fn append(&mut self, data: &Slice) -> Status

Trait Implementations

impl Default for FileState

fn default() -> FileState

| FileStates are reference counted. | The initial reference count is zero | and the caller must call Ref() at least | once. |

impl Drop for FileState

fn drop(&mut self)

| Private since only Unref() should be | used to delete it. |
