Struct RandomAccessFileImpl

pub struct RandomAccessFileImpl { /* private fields */ }

Expand description

Implementations§

impl RandomAccessFileImpl

pub fn new(file: *mut FileState) -> RandomAccessFileImpl

Trait Implementations§

impl Drop for RandomAccessFileImpl

fn drop(&mut self)

Executes the destructor for this type. Read more

impl GetName for RandomAccessFileImpl

fn get_name(&self) -> &'static str

| Get a name for the file, only for error | reporting |

impl RandomAccessFileRead for RandomAccessFileImpl

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

| Read up to “n” bytes from the file starting | at “offset”. “scratch[0..n-1]” may be | written by this routine. Sets “*result” to | the data that was read (including if fewer | than “n” bytes were successfully read). May | set “*result” to point at data in | “scratch[0..n-1]”, so “scratch[0..n-1]” must | be live when “*result” is used. If an error | was encountered, returns a non-OK status. | | Safe for concurrent use by multiple threads.
