-The function signatures are:
-
-```rust
-fn write<W: io::Write, V: itoa::Integer>(writer: W, value: V) -> io::Result<usize>;
-
-fn fmt<W: fmt::Write, V: itoa::Integer>(writer: W, value: V) -> fmt::Result;
-```
-
-where `itoa::Integer` is implemented for i8, u8, i16, u16, i32, u32, i64, u64,
-i128, u128, isize and usize.
-
-The `write` function is only available when the `std` feature is enabled
-(default is enabled). The return value gives the number of bytes written.
