133-137: Implementation looks good but could be optimizedThe implementation is correct and consistent with other From implementations. However, since
StringimplementsDeref<Target=str>, we could avoid an extra method call by usingas_str()directly.Consider this minor optimization:
impl From<&String> for CheetahString { fn from(s: &String) -> Self { - CheetahString::from_slice(s) + CheetahString::from_slice(s.as_str()) } }This makes the string slice conversion explicit and might be slightly more efficient by avoiding the implicit deref coercion.
133-137: Add documentation for the new From implementationThe implementation would benefit from documentation explaining the conversion behavior, consistent with Rust's documentation practices.
Consider adding documentation:
+/// Converts a reference to a String into a CheetahString. +/// +/// This implementation creates a new CheetahString by copying the contents +/// of the referenced String. +/// +/// # Examples +/// +/// ``` +/// use cheetah_string::CheetahString; +/// +/// let original = String::from("hello"); +/// let cheetah = CheetahString::from(&original); +/// assert_eq!(cheetah, "hello"); +/// ``` impl From<&String> for CheetahString { fn from(s: &String) -> Self { CheetahString::from_slice(s) } }
