BOTW resource size table (RSTB) library in Rust
A quick and easy library for manipulating the resource size table (RSTB) from The Legend of Zelda:
Breath of the Wild in Rust. Can edit an RSTB directly or convert to and from a JSON representation.
Basic usage to manipulate an RSTB file:
```rust
use std::fs::read;
use rstb::{ResourceSizeTable, Endian};
let buff: Vec = read("ResourceSizeTable.product.srsizetable").unwrap();
// Read RSTB from data, automatically decompressing if yaz0 compressed
let mut table: ResourceSizeTable = ResourceSizeTable::frombinary(buff, Endian::Big).unwrap();
// Set the size for a resource
table.setsize("Map/MainField/A-1/A-1Dynamic.mubin", 777u32);
// Check the size
asserteq!(
table.getsize("Map/MainField/A-1/A-1Dynamic.mubin").unwrap(),
777
);
// Dump to JSON
let jsontable = table.totext().unwrap();
// From JSON back to RSTB
let newtable = ResourceSizeTable::fromtext(&jsontable).unwrap();
// Write new binary copy, and we'll yaz0 compress it
let outbuf: Vec = table.to_binary(Endian::Big, true).unwrap();
```
Also provides functions for calculating resource sizes:
```rust
use std::fs::read;
use rstb::calc::*;
// Calculate RSTB value for file on disk
asserteq!(
calculatesize(
"A-1_Dynamic.smubin",
Endian::Big,
false
).unwrap()
.unwrap(),
48800
);
// Or we can calculate from a buffer if we provide the file extension
let buf: Vec = read("A-1Dynamic.smubin").unwrap();
asserteq!(
calculatesizewith_ext(
&buf,
".smubin",
Endian::Big,
false
).unwrap(),
48800
);
```
