impl TryFrom<i32> for u32 {
    type Error = TryFromIntError;
    fn try_from(value: i32) -> Result<i64, TryFromIntError>;

- Prefix for methods that can fail, returning a `Result`.

TryFrom is a From-like trait for types whose single-value constructors might fail in some way.
Ask: Why aren’t Vec::get and other similar methods called try_get?

Methods are named get if they return a reference to an existing value and return an Option instead of Result because there is only one failure mode. For example, only “index out of bounds” for Vec::get, and “key does not exist” for HashMap::get.
