 - Strong static type checking
 - Tree shaking friendly design
 - Support for little-endian, big-endian, and dynamic endian values.

+# Usage
+
+## Fixed Endianness
+
+Endianness can be defined for each individual member.
+
+```ts
+import { memberU16, memberU8, Struct } from '@hqtsm/struct';
+
+export class Example extends Struct {
+	declare public readonly ['constructor']: typeof Example;
+
+	declare public alpha: number;
+
+	declare public beta: number;
+
+	declare public gamma: number;
+
+	public static override readonly BYTE_LENGTH: number = ((o) => {
+		o += memberU16(this, 'alpha', o, true);
+		o += memberU16(this, 'beta', o, false);
+		o += memberU8(this, 'gamma', o);
+		return o;
+	})(super.BYTE_LENGTH);
+}
+
+const data = new Uint8Array(Example.BYTE_LENGTH);
+
+const example = new Example(data.buffer);
+example.alpha = 0xABCD;
+example.beta = 0xBCDE;
+example.gamma = 123;
+console.assert(data.join(', ') === '205, 171, 188, 222, 123');
+```
+
+## Dynamic Endianness
+
+Using the endian passed into the constructor, or host endianness.
+
+```ts
+import { memberU16, Struct } from '@hqtsm/struct';
+
+export class Example extends Struct {
+	declare public readonly ['constructor']: typeof Example;
+
+	declare public alpha: number;
+
+	declare public beta: number;
+
+	public static override readonly BYTE_LENGTH: number = ((o) => {
+		o += memberU16(this, 'alpha', o);
+		o += memberU16(this, 'beta', o);
+		return o;
+	})(super.BYTE_LENGTH);
+}
+
+const data = new Uint8Array(Example.BYTE_LENGTH);
+
+const exampleLE = new Example(data.buffer, 0, true);
+exampleLE.alpha = 0xABCD;
+exampleLE.beta = 0xBCDE;
+console.assert(data.join(', ') === '205, 171, 222, 188');
+
+const exampleBE = new Example(data.buffer, 0, false);
+exampleBE.alpha = 0xABCD;
+exampleBE.beta = 0xBCDE;
+console.assert(data.join(', ') === '171, 205, 188, 222');
