[−][src]Trait concat_reader::FileConcatRead
FileConcatRead
is a kind of ConcatRead
which can provide information about the file currently read.
Example
use std::io; use std::io::prelude::*; use std::path::Path; use crate::concat_reader::*; fn main() -> io::Result<()> { let files = vec!["/path/to/file_1", "/path/to/file_2", "/path/to/file_3"]; let mut f = concat_path(files); assert!(f.file_path().is_none()); let mut buffer = [0; 10]; f.read(&mut buffer)?; assert_eq!(f.file_path(), Some(Path::new("/path/to/file_1"))); Ok(()) }
Required methods
fn file_path(&self) -> Option<&Path>
Returns the path to the current File
being read from.
use std::io; use std::io::prelude::*; use crate::concat_reader::*; fn main() -> io::Result<()> { let files = vec!["/path/to/file_1", "/path/to/file_2", "/path/to/file_3"]; let mut f = concat_path(files); let mut buffer = [0; 1]; //read 1 bytes from the reader f.read_exact(&mut buffer); println!("read from {}", f.file_path().unwrap().display()); //skip to next file in reader f.skip(); /// //read 1 bytes from the reader f.read_exact(&mut buffer); println!("read from {}", f.file_path().unwrap().display()); Ok(()) }
