pistonite-cu 0.8.4

//! # Cu = Copper
//! Batteries-included common utils
//!
//! (If you are viewing this on docs.rs, please use the [self-hosted
//! version](https://cu.pistonite.dev) instead)
//!
//! # Quick start
//! When installing, rename the crate to `cu` in `Cargo.toml`:
//! ```toml
//! # Cargo.toml
//! # ...
//! [dependencies.cu]
//! package = "pistonite-cu"
//! version = "..." # check by running `cargo info pistonite-cu`
//! features = [ "full" ] # see docs
//!
//! [dependencies]
//! # ...
//! ```
//!
//! The goal with using `cu` is use only one `use` statement:
//! ```rust
//! # use pistonite_cu as cu;
//! use cu::pre::*;
//! ```
//! This brings into scope a few things:
//! - Traits that are expected to be used, such as `anyhow::Context`
//! - Re-exports of modules, such as `json` if the `json` feature is enabled
//!
//! If a function or type is not included with `pre::*`, that means the canonical
//! style for using it is with the full path, for example, you would write:
//!
#![cfg_attr(not(feature = "fs"), doc = "```rust,ignore")]
#![cfg_attr(feature = "fs", doc = "```rust,no_run")]
//! # use pistonite_cu as cu;
//! use cu::pre::*;
//!
//! fn read_file() -> cu::Result<()> {
//!     cu::fs::read_string("foo/bar.txt")?;
//!     cu::info!("successfully read file");
//!     Ok(())
//! }
//! ```
//!
//! instead of the below:
#![cfg_attr(not(feature = "fs"), doc = "```rust,ignore")]
#![cfg_attr(feature = "fs", doc = "```rust,no_run")]
//! # use pistonite_cu as cu;
//! use cu::pre::*;
//! use cu::{Result, fs, info};
//! // ^ don't include extra uses!
//! //   the biggest disadvantage of this is
//! //   it's easy to confuse with types in the standard library
//!
//! fn read_file() -> Result<()> {
//!     fs::read_string("foo/bar.txt")?;
//!     info!("successfully read file");
//!     Ok(())
//! }
//! ```
//!
