This library provides methods for converting between numeric types. In Rust, when you need to convert basic numeric types to another type, you need to use the as keyword, for example:
```rust
1u8 as u16
```
This library provides two conversion methods that can provide the same functionality:
1.
```rust
let v_u16=u8tou16(1u8)
```
2.
```rust
let v_u16=1u8.tou16()
```
