+
+This crate provides fast functions for printing integer primitives to an
+[`io::Write`] or a [`fmt::Write`]. The implementation comes straight from
+[libcore] but avoids the performance penalty of going through
+[`fmt::Formatter`].
+
+See also [`dtoa`] for printing floating point primitives.
+
+*Version requirement: rustc 1.0+*
+
+[`io::Write`]: https://doc.rust-lang.org/std/io/trait.Write.html
+[`fmt::Write`]: https://doc.rust-lang.org/core/fmt/trait.Write.html
+[libcore]: https://github.com/rust-lang/rust/blob/b8214dc6c6fc20d0a660fb5700dca9ebf51ebe89/src/libcore/fmt/num.rs#L201-L254

+## Performance (lower is better)
+

+
+<br>
+
+## Examples
+
+```rust
+use std::{fmt, io};
+
+fn demo_itoa_write() -> io::Result<()> {
+    // Write to a vector or other io::Write.
+    let mut buf = Vec::new();
+    itoa::write(&mut buf, 128u64)?;
+    println!("{:?}", buf);
+
+    // Write to a stack buffer.
+    let mut bytes = [0u8; 20];
+    let n = itoa::write(&mut bytes[..], 128u64)?;
+    println!("{:?}", &bytes[..n]);
+
+    Ok(())
+}
+
+fn demo_itoa_fmt() -> fmt::Result {
+    // Write to a string.
+    let mut s = String::new();
+    itoa::fmt(&mut s, 128u64)?;
+    println!("{}", s);
+
+    Ok(())
+}
+```
+
+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. 128-bit integer support requires rustc 1.26+ and
+the `i128` feature of this crate enabled.
+
+The `write` function is only available when the `std` feature is enabled
+(default is enabled). The return value gives the number of bytes written.
