Struct Lines 

pub struct Lines<R> { /* private fields */ }

Optimized streaming interface for reading lines in reverse

Implementations

impl<R: AsyncRead + AsyncSeek + Unpin> Lines<R>

pub async fn next_line(&mut self) -> IoResult<Option<String>>

Returns the next line in reverse order, following tokio patterns

Examples

use async_rev_buf::RevBufReader;
use std::io::Cursor;

async fn example() -> std::io::Result<()> {
    let data = "first line\nsecond line\nthird line";
    let cursor = Cursor::new(data);
    let reader = RevBufReader::new(cursor);
    let mut lines = reader.lines();

    // Read lines in reverse order
    assert_eq!(lines.next_line().await?, Some("third line".to_string()));
    assert_eq!(lines.next_line().await?, Some("second line".to_string()));
    assert_eq!(lines.next_line().await?, Some("first line".to_string()));
    assert_eq!(lines.next_line().await?, None);
    Ok(())
}

pub fn get_ref(&self) -> &RevBufReader<R>

Returns a reference to the underlying RevBufReader

pub fn get_mut(&mut self) -> &mut RevBufReader<R>

Returns a mutable reference to the underlying RevBufReader

pub fn into_inner(self) -> RevBufReader<R>

Consumes this Lines, returning the underlying reader

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

Formats the value using the given formatter.
