static_table 0.3.0

# (`static_table`) Cook tables at compiler time

The library provides a macros to build a pretty tables at compile time.

There's 2 types of tables you can buid.

1. Standart adjusted tables (`static_table::static_table`).
2. Not adjusted, floating tables (`static_table::pool_table`).

To find a more features and settings which you can use with the macros please check out the documentation ([docs.rs](https://docs.rs/static_table)).

## Get started

Add the library to your `Cargo.toml`.

```toml
# Cargo.toml
[dependencies]
static_table = "0.2"
```

```rust
use static_table::static_table;

static LANG_LIST: &str = static_table!([
    ["name", "designed by", "first release"],
    ["C", "Dennis Ritchie", "1972"],
    ["Go", "Rob Pike", "2009"],
    ["Rust", "Graydon Hoare", "2010"],
    ["Hare", "Drew DeVault", "2022"],
]);

fn main() {
    println!("{LANG_LIST}")
}
```

You can even use the macros in the documentation

```rust
/// Add joins 2 integers together to get a sum.
/// 
/// ```
#[doc = static_table::static_table!([
    ["a", "b", "result"],
    ["1", '2', '3'],
    ["2", '2', '4']
])]
/// ```
pub fn add(left: usize, right: usize) -> usize {
    left + right
}
```

## Binary size concern

It's something you shall be aware of.
Using `static_table` MIGHT increase a binary size, because the table will be stored as actuall symbols in a static section of a binary file (ELF, PE etc.).

I have run a few tests in this regard.
And a binary which used `static_table` has SUBSTATIANALY smaller size than
a binary with a build table at runtime using `lazy_static`/`once_cell`.
I am not sure though why it is a case.

```table
                debug mode      release mode
static_table    13497232        4501576
runtime table   12031120        4156024
```
