Rust Util Collection, a simple and friendly error-chain, with many useful utils as an addition.
The painful experience of using error-chain gave birth to this project. It can adapt to almost all scenes without any special implementation.
``` [features] default = ["ansi"] ansi = [] compact = []
rich = ["uau", "cmd"] uau = ["nix", "rand"] cmd = [] ```

make doc
Tips: you can easily implement your own
Errortype.
```rust use ruc::{err::*, *};
struct CustomErr(i32);
fn willpanic() { let l1 = || -> Result<()> { Err(eg!("The final error message!")) }; let l2 = || -> Result<()> { l1().c(d!()) }; let l3 = || -> Result<()> { l2().c(d!("A custom message!")) }; let l4 = || -> Result<()> { l3().c(d!("ERRUNKNOWN")) }; let l5 = || -> Result<()> { l4().c(d!(@CustomErr(-1))) };
pnk!(l5());
} ```
features = ["ansi"]
```
