Struct fbxcel::parser::binary::SeekableSource

pub struct SeekableSource<R> { /* fields omitted */ }

Reader with position info and seek feature.

This wrapper doesn't manage offset, i.e. the start of the source stream should be the start of the FBX data.

Methods

impl<R: Read + Seek> SeekableSource<R>

fn new(source: R) -> Self

Creates a new SeekableSource.

Trait Implementations

impl<R: Read> Read for SeekableSource<R>

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

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

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

Read the exact number of bytes required to fill buf.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into buf.

fn by_ref(&mut self) -> &mut Self

Creates a "by reference" adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

Transforms this Read instance to an Iterator over its bytes.

fn chars(self) -> Chars<Self>

Unstable (io)

: the semantics of a partial read/write of where errors happen is currently unclear and may change

Transforms this Read instance to an Iterator over chars.

fn chain<R>(self, next: R) -> Chain<Self, R> where R: Read

Creates an adaptor which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

Creates an adaptor which will read at most limit bytes from it.

impl<R: Read + Seek> Seek for SeekableSource<R>

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

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

impl<R> Debug for SeekableSource<R>

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

Formats the value using the given formatter.

impl<R: Read + Seek> ParserSource for SeekableSource<R>

fn position(&self) -> u64

Returns the current position from the start of the stream.

fn skip_to(&mut self, dest_pos: u64) -> Result<()>

Skips to the given position.
