Struct ole::EntrySlice

pub struct EntrySlice<'s> { /* fields omitted */ }

Slice of the content of the entry.

This is not an ordinary slice, because OLE files are like FAT system: they are based on sector and SAT. Therefore, a stream can be fragmented through the file.

Basic example

use ole::Reader;
use std::io::Read;
let mut parser =
      Reader::<std::fs::File>::from_path("assets/Thumbs.db").unwrap();

let entry = parser.iterate().next().unwrap();
let mut slice = parser.get_entry_slice(entry).unwrap();
// Read the first 42 bytes of the entry;
let mut buf = [0u8; 42];
let nread = slice.read(&mut buf).unwrap();

Methods

impl<'s> EntrySlice<'s>

pub fn len(&self) -> usize

Returns the length of the slice, therefore the length of the entry.

Trait Implementations

impl<'s> Read for EntrySlice<'s>

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

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

unsafe fn initializer(&self) -> Initializer

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

Determines if this Reader can work with buffers of uninitialized memory.

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, appending them to buf.

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

Read the exact number of bytes required to fill 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>

🔬 This is a nightly-only experimental API. (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 [char]s.

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.
