Exports your types to other languages, currently supporting TypeScript.
## Install
Add to your `Cargo.toml`
```toml
[dependencies]
burrtype = { version = "0.2", features = ["typescript"] }
```
## Usage
### Preparing your types
Decorate your types with the `Burr` derive macro.
```rust
use burrtype::prelude::*;
#[derive(Burr)]
pub struct Foo(u64);
#[derive(Burr)]
pub struct Bar(Foo);
```
For types that don't derive `Burr`, such as those from third-party crates, use an attribute to treat fields as different types:
```rust
#[derive(serde::Serialize, serde::Deserialize, Debug)]
pub struct PhantomType(pub u64);
#[derive(Burr)]
pub struct Foo {
#[burr(type = u64)]
pub foo: PhantomType,
}
```
### Exporting your types
In your `build.rs` or another binary, we can create an exporter and optionally configure it. The exporter and its components behave as builder patterns.
```rust
Burrxporter::new()
// auto-registered types depended on by your types will be exported here
.with_default_mod("common")
```
Add your types using modules to organize them. This module tree typically translates to the file structure being produced - with one file per module - but language constraits, features, or options can change this behavior.
```rust
.with_mod(BurrMod::new("bar")
.with_type::<Bar>()
)
```
Export to one or more targets.
```rust
// outputs ./ts/common.ts and ./ts/bar.ts
.export("ts", TypeScript::new())?
// bundles all exported types into a single file
.export("out/bundled.ts", TypeScript::new().with_file_map(ModFileMap::Inline))?
```
See these concepts in action in [the example](examples/sandbox/).

## Desired features going forward
- Replace panics with errors
- tests
- Rust target
- Support the same set of common features as TypeScript
- Generic types?
