Scalar Types

The following table lists the primitive types in Rust and their equivalent in C# and .NET:

Notes:

1. char in Rust and Char in .NET have different definitions. In Rust, a char is 4 bytes wide that is a Unicode scalar value, but in .NET, a Char is 2 bytes wide and stores the character using the UTF-16 encoding. For more information, see the Rust char documentation.

2. While a unit () (an empty tuple) in Rust is an expressible value, the closest cousin in C# would be void to represent nothing. However, void isn't an expressible value except when using pointers and unsafe code. .NET has ValueTuple that is an empty tuple, but C# does not have a literal syntax like () to represent it. ValueTuple can be used in C#, but it's very uncommon. Unlike C#, F# does have a unit type like Rust.

3. While void and object are not scalar types (even though scalars like int are sub-classes of object in the .NET type hierarchy), they have been included in the above table for convenience.
