Struct FileReader 

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

A file wrapper that implements ReaderAt across platforms.

Implementations

impl FileReader

pub fn into_inner(self) -> File

Trait Implementations

impl Debug for FileReader

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

Formats the value using the given formatter.

impl From<File> for FileReader

fn from(file: File) -> Self

Converts to this type from the input type.

impl ReaderAt for FileReader

fn read_at(&self, buf: &mut [u8], offset: u64) -> Result<usize>

Read bytes from the reader at a specific offset

fn read_exact_at(&self, buf: &mut [u8], offset: u64) -> Result<()>

Sibling to read_exact, but at an offset

impl Seek for FileReader

fn seek(&mut self, pos: SeekFrom) -> Result<u64>

Seek to an offset, in bytes, in a stream.

fn rewind(&mut self) -> Result<(), Error>

Rewind to the beginning of a stream.

fn stream_len(&mut self) -> Result<u64, Error>

🔬This is a nightly-only experimental API. (seek_stream_len)

Returns the length of this stream (in bytes).

fn stream_position(&mut self) -> Result<u64, Error>

Returns the current seek position from the start of the stream.

fn seek_relative(&mut self, offset: i64) -> Result<(), Error>

Seeks relative to the current position.
