Microsoft's Rust guide for C#/.NET developers

Having never touched rust before, this seems like a good launching point. Curious though - why did Microsoft create this? Presumably they would be more interested in a C#/.NET guide for Rust developers.

Microsoft employs a number of people writing Rust code, with more on the way. I don’t have specific context as to why this guide was created, but it’s not like .NET languages are the only languages used at Microsoft.

f16 in Rust is equivalent to float in C#

f32 in Rust is equivalent to double in C#

f64 in Rust is equivalent to decimal in C#

correcting a typo on this page:

Don't think that's quite right. `float` has 4 bytes, and `double` has 8. The `decimal` type has 16 bytes and does all it's arithmetic in base 10.

Are you quoting some old version? Because the page correctly states that Rust's f32 is C#'s float.

[jjtheblunt → CrimsonCape]

Where are you getting what you wrote?

Rust doesn't (March 2024) have f16. And the other correspondences you wrote are wrong.

There's a crate (several it seems) which realizes an f16 with arithmetic using u16, for example.

[kcb → CrimsonCape]

That doesn't sound right.

[bloqs → CrimsonCape]

This smells like it was written by an LLM

No it doesn’t.
