Implementations

impl SequentialFileImpl

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

Trait Implementations

impl Drop for SequentialFileImpl

fn drop(&mut self)

Executes the destructor for this type.

impl GetName for SequentialFileImpl

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

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

impl SequentialFileRead for SequentialFileImpl

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

| Read up to “n” bytes from the file. “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. | | REQUIRES: External synchronization |

impl SequentialFileSkip for SequentialFileImpl

fn skip(&mut self, n: u64) -> Status

| Skip “n” bytes from the file. This is | guaranteed to be no slower that reading the | same data, but may be faster. | | If end of file is reached, skipping will stop | at the end of the file, and Skip will return | OK. | | REQUIRES: External synchronization
