Both Rust and F# use postfixes on numbers to indicate the type if you want to choose something besides the default 32-bit int or 64-bit float. In Rust you can choose either declaring the type or adding a postfix, while in F# it's the postfix that does it. Thus:

* Rust `let x: u8 = 5` or `let x = 5u8` is F# `let x = 5uy`. (**u**nsigned b**y**te)
* Rust `let x: u16 = 5` or `let x = 5u16` is F# `let x = 5us`. (**u**nsigned **s**hort)
* Rust `let x: u32 = 5` or `let x = 5u32` is F# `let x = 5u`. (**u**nsigned)
* Rust `let x: u64 = 5` or `let x = 5u64` is F# `let x = 5UL`. (**U**nsigned **L**ong)
* Rust `let x: i8 = 5` or `let x = 5i8` is F# `let x = 5y`. (b**y**te)
* Rust `let x: i16 = 5` or `let x = 5i16` is F# `let x = 5s`. (**s**hort)
* Rust `let x: i32 = 5` or `let x = 5i32` is F# `let x = 5`. (no postfix here - it's the default)
* Rust `let x: i64 = 5` or `let x = 5i64` is F# `let x = 5L`. (**L**ong)
* Rust `let x: f32 = 5.0` or `let x = 5.0f32` is F# `let x = 5.0f` or `let x = 5f`.
* Rust `let x: f64 = 5.0` or `let x = 5.0f64` is F# `let x = 5.0`. (no postfix here - it's the default)
* Rust `let x: u8 = 5` or `let x = 5u8` is F# `let x = uint8 5` or `let x = 5uy`. (**u**nsigned b**y**te)
* Rust `let x: u16 = 5` or `let x = 5u16` is F# `let x = uint16 5` or `let x = 5us`. (**u**nsigned **s**hort)
* Rust `let x: u32 = 5` or `let x = 5u32` is F# `let x = uint32 5` or `let x = 5u`. (**u**nsigned)
* Rust `let x: u64 = 5` or `let x = 5u64` is F# `let x = uint64 5` or `let x = 5UL`. (**U**nsigned **L**ong)
* Rust `let x: i8 = 5` or `let x = 5i8` is F# `let x = int8 5` or `let x = 5y`. (b**y**te)
* Rust `let x: i16 = 5` or `let x = 5i16` is F# `let x = int16 5` or `let x = 5s`. (**s**hort)
* Rust `let x: i32 = 5` or `let x = 5i32` is F# `let x = int32 5` or `let x = 5`. (no postfix here - it's the default)
* Rust `let x: i64 = 5` or `let x = 5i64` is F# `let x = int64 5` or `let x = 5L`. (**L**ong)
* Rust `let x: f32 = 5.0` or `let x = 5.0f32` is F# `let x = float32 5` or `let x = 5.0f` or `let x = 5f`.
* Rust `let x: f64 = 5.0` or `let x = 5.0f64` is F# `let x = float 5` or `let x = 5.0`. (no postfix here - it's the default)

And both Rust and F# have the option of putting _ in between numbers to make them readable. This code works in both languages:
