# BinaryStruct.ts
A small, performant Typescript decorator-based module for working directly with
raw binary data structures.
## Examples
### Basic Usage
```ts
import { BinaryStruct, BinaryType, sizeOf, binaryStruct, binaryField } from "binary-struct-ts";
@binaryStruct()
class ExampleStruct extends BinaryStruct
{
@binaryField(BinaryType.Int32)
id: number;
@binaryField(BinaryType.Float32)
value: number;
@binaryField(BinaryType.Uint8)
isDeleted: number;
@binaryField(BinaryType.BinaryStruct, AnotherStruct)
details: AnotherStruct;
};
const data = new ExampleStruct(new ArrayBuffer(sizeOf(ExampleStruct)));
data.id = 1234;
data.value = 3.14;
data.details = anotherStructInstance;
```
### Read Structured Data
```ts
const data = new ExampleStruct(arrayBuffer, offsetBytes);
id = data.id;
value = data.value;
detailsValue = data.details.value;
```
### Copy Data
```ts
const src = new ExampleStruct(arrayBuffer, srcOffsetBytes);
const dst = new ExampleStruct(arrayBuffer, dstOffsetBytes);
dst.copyFrom(src);
```
### Additional Options
```ts
@binaryStruct({ endianness: Endianness.BigEndian,
packingStrategy: new AlignedPackingStrategy(4) })
class ExampleStruct extends BinaryStruct
{
@binaryField(BinaryType.Int32)
id: number;
@binaryField(BinaryType.Float32)
value: number;
@binaryField(BinaryType.Uint8)
isDeleted: number;
@binaryField(BinaryType.BinaryStruct, AnotherStruct)
details: AnotherStruct;
};
```
