[SOLVED] Converting a string slice to a slice of 4 bytes

[severe spoke]

Hi all.

Is it possible to convert a &str to a [u8; 4]? My ultimate goal is to implement FromStr for a custom type that wraps [u8; 4], so that it's possible to create an instance of it from a &str.

[uncut pawn]

first use .as_bytes() on the &str to get &[u8]

then use .try_into() on that to convert it to [u8; 4] (and fail if the length is wrong)

Ah thanks a lot. That worked!

Note that you can't represent all [u8; 4]s with strings, as strings only support UTF-8 data. If the data can be any possible [u8; 4], you shouldn't turn it into bytes in a string in the first place.
