Crate nom_bufreader_rp

Expand description

This crate provides a BufReader alternative that can be used with nom parsers

It will hide for you the Incomplete handling in nom for streaming parsers, retrying and refilling buffers automatically.

For synchronous io, use bufreader::BufReader, while for asynchronous IO, you should use async_bufreader::BufReader

Examples

sync

use nom_bufreader::bufreader::BufReader;
use nom_bufreader::{Error, Parse};
use std::{net::TcpListener, str::from_utf8};

fn main() -> Result<(), Error<()>> {
    let listener = TcpListener::bind("127.0.0.1:8080")?;
    let mut i = BufReader::new(listener.incoming().next().unwrap()?);

    // method, space and path are nom parsers
    let m = i.parse(method)?;
    let _ = i.parse(space)?;
    let p = i.parse(path)?;
    println!("got method {}, path {}", m, p);
    Ok(())
}

async

tokio

use nom_bufreader::async_bufreader::BufReader;
use nom_bufreader::{AsyncParse, Error};
use std::str::from_utf8;
use tokio_util::compat::TokioAsyncReadCompatExt;
use tokio::net::TcpListener;

#[tokio::main]
async fn main() -> Result<(), Error<()>> {
    let listener = TcpListener::bind("127.0.0.1:8080").await?;
    let mut i = BufReader::new(listener.accept().await?.0.compat());

    let m = i.parse(method).await?;
    let _ = i.parse(space).await?;
    let p = i.parse(path).await?;
    println!("got method {}, path {}", m, p);
    Ok(())
}

async-std

use nom_bufreader::async_bufreader::BufReader;
use nom_bufreader::{AsyncParse, Error};
use std::str::from_utf8;
use async_std::net::TcpListener;

#[async_std::main]
async fn main() -> Result<(), Error<()>> {
    let listener = TcpListener::bind("127.0.0.1:8080").await?;
    let mut i = BufReader::new(listener.accept().await?.0);

    let m = i.parse(method).await?;
    let _ = i.parse(space).await?;
    let p = i.parse(path).await?;
    println!("got method {}, path {}", m, p);
    Ok(())
}
