Struct ole::EntrySlice
[−]
[src]
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();
