Documentation correction for time complexity of char_at method
Category
Correctness Code Snippet
/// This method has O(n) complexity.
pub fn View::char_at(self : View, index : Int) -> Char Recommendation
The updated documentation correctly states O(1) complexity and clarifies the index meaning Reasoning
Accurate documentation is crucial for API users to make informed decisions. The previous O(n) complexity claim could mislead developers into avoiding this method in performance-critical code paths
Consider adding more detailed parameter documentation

Maintainability Code Snippet
pub fn View::char_at(self : View, index : Int) -> Char Recommendation
Add parameter documentation explaining that 'index' is a byte offset:
/// @param index: The byte offset into the string (not character position) Reasoning
While the comment mentions this isn't the n-th character, explicit parameter documentation would make the API more self-documenting and prevent misuse
Consider adding example usage in documentation

/// Returns the Unicode character at the given index. Note this is not the n-th character. Recommendation
Add example usage:
///|
/// Returns the Unicode character at the given index. Note this is not the n-th character.
/// Example:
/// /// let v = View::from("hello") /// let c = v.char_at(0) // Returns 'h' /// Reasoning
Examples in documentation help users understand the correct usage pattern, especially for methods where the index parameter behavior might not be immediately obvious
