### A crate for multiple types of asserts that don't exist in the standard library
# Rationale
There are several kinds of problems that I had faced while writing tests, especially when writing comparator tests.
The output from the existing macros, were providing _vague_ outputs while debugging which made me write this crate.
I had created an RFC, but neverthless it was rejected as there were not enough use cases. I am not too sure about others, but I find myself writing multiple tests that make use of these asserts.
# Importing and using
Add these lines to your rust application:
```rust
#[macro_use]
extern crate all_asserts;
```
And now you can use the asserts wherever you like!
On Panic you should get something like this (the example is from `assert_lt!`):
```
thread 'main' panicked at 'assertion failed: `(left < right) but here (left >= right)`
left: `100`,
right: `200`', src/main.rs:79:5
```
Isn't that much better than what the current macros provide? Well, I'll leave you to decide!
# Usage of the macros
The name of the assert pretty much tells you everything:
- `assert_gt!(a, b)` -> Will panic if a is not greater than b
- `assert_ge!(a, b)` -> Will panic if a is not greater than or equal to b
- `assert_lt!(a, b)` -> Will panic if a is not less than b
- `assert_le!(a, b)` -> Will panic if a is not greater than or equal to b
# Building
Simply run:
```shell
$ git clone https://github.com/ohsayan/all_asserts.git
$ cd all_asserts
$ cargo build
```
And for testing:
```shell
$ cargo test
```
