无标准库依赖（no_std）；\n- 可选的 half 浮点数支持；\n\n## 使用示例\n\n### 基本用法\n\n```rust\nuse digit_layout::{DigitLayout, LayoutContent};\n\n// 创建无符号整数类型布局\nlet u8_layout = DigitLayout::unsigned(8, 1);\nassert_eq!(u8_layout.to_string(), \"u8\");\n\n// 创建浮点数类型布局\nlet f32_layout = DigitLayout::real(8, 23, 1);\nassert_eq!(f32_layout.to_string(), \"f32_e8m23\");\n\n// 创建自定义类型布局\nlet custom_layout = DigitLayout::named(\"custom\", 1, 4);\nassert_eq!(custom_layout.to_string(), \"custom\");\n```\n\n### 数组类型\n\n```rust\nuse digit_layout::DigitLayout;\n\n// 创建无符号整数数组布局\nlet u8_array = DigitLayout::unsigned(8, 4);\nassert_eq!(u8_array.to_string(), \"[u8; 4]\");\n\n// 创建浮点数数组布局\nlet f32_array = DigitLayout::real(8, 23, 4);\nassert_eq!(f32_array.to_string(), \"[f32_e8m23; 4]\");\n```\n\n### 解码布局\n\n```rust\nuse digit_layout::{DigitLayout, LayoutContent};\n\n// 解码无符号整数布局\nlet u8_layout = DigitLayout::unsigned(8, 1);\nmatch u8_layout.decode() {\n    LayoutContent::Unsigned { width } =\u003e {\n        assert_eq!(width, 8);\n    }\n    _ =\u003e panic!(\"Expected unsigned layout\"),\n}\n\n// 解码浮点数布局\nlet f32_layout = DigitLayout::real(8, 23, 1);\nmatch f32_layout.decode() {\n    LayoutContent::Real { exponent, mantissa } =\u003e {\n        assert_eq!(exponent, 8);\n        assert_eq!(mantissa, 23);\n    }\n    _ =\u003e panic!(\"Expected real layout\"),\n}\n```\n\n## 性能测试\n\n项目包含一个性能测试示例，可以测量各种操作的执行时间。运行性能测试：\n\n```bash\ncargo run --example benchmark\n```\n\n性能测试会测量以下操作的执行时间：\n\n1. 创建布局\n   - 创建无符号整数布局；\n   - 创建浮点数布局；\n   - 创建自定义布局；\n\n2. 解码布局\n   - 解码无符号整数布局；\n   - 解码浮点数布局；\n   - 解码自定义布局；\n\n测试结果会显示每个操作的平均执行时间。\n\n## 文档\n\n完整的 API 文档可以在 [docs.rs](https://docs.rs/digit-layout) 上找到。\n\n## 贡献\n\n欢迎提交 Issue 和 Pull
