A personal utility crate.
Adds reexports of color_eyre
, piping traits (Pipe
, Inspect
, Lay
), a block_on
implementation for futures, reexports thiserror
, and reexports tracing
+ tracing_subscriber
(as tracing_utils::subscriber
) with a prelude and quick init function.
Run cew::init()
to initialize color_eyre
cew::R
is short for color_eyre::Result
cew::U
is short for color_eyre::Result<()>
cew::e!(..)
is short for color_eyre::eyre::eyre!(..)
cew::me!(..)
is short for Err(color_eyre::eyre::eyre!(..))
The Pipe
, Inspect
, and Lay
traits provide functions to reduce the amount of stacked parenthesis in long method chains, like the tap
crate.
The tracing_subscriber
quick init should be overriden with a custom impl if needed, but it gets you started quickly.
Usage:
use cew::prelude::*;
fn main() -> cew::U {
cew::init()?;
// turbofish is needed here, as the type parameters cannot be inferred.
cew::tracing::init_filtered_w_env::<String, cew::tracing::Layer>(
cew::tracing::fmt_layer().without_time(),
cew::tracing::LevelFilter::INFO,
[]
)?;
info!("Traced").
cew::me!("Error");
}
