[v0.2.0] - 2025-06-29

• add: trim Removes all leading and trailing Unicode code points in the given cutset from the string. Unicode-aware.
• add: trim_func Removes all leading and trailing Unicode code points from the string that satisfy the given predicate function. Unicode-aware.
• add: trim_left Removes all leading Unicode code points in the given cutset from the string. Unicode-aware.
• add: trim_left_func Removes all leading Unicode code points from the string that satisfy the given predicate function. Unicode-aware.
• add: trim_right Removes all trailing Unicode code points in the given cutset from the string. Unicode-aware.
• add: trim_right_func Removes all trailing Unicode code points from the string that satisfy the given predicate function. Unicode-aware.
• add: trim_space Removes all leading and trailing Unicode whitespace from the string. Unicode-aware.
• add: trim_suffix Removes the provided trailing suffix, if present. Operates on bytes, not code points.
• add: to_lower Converts all ASCII letters in the string to lowercase. (Full Unicode lowercasing not yet supported.)
• add: to_title Converts all ASCII letters in the string to uppercase (title case). (Full Unicode title case not yet supported.)
• add: to_upper Converts all ASCII letters in the string to uppercase. (Full Unicode uppercasing not yet supported.)
• add: to_camel_case Converts words separated by space, underscore, or hyphen to camelCase. The first word is lowercased, subsequent words are capitalized. Handles all-uppercase words and preserves leading/trailing separators.
• add: to_kebab_case Converts a string to kebab-case. Uppercase ASCII letters are converted to lowercase. Word boundaries are detected at transitions and replaced with a single hyphen. Multiple separators are normalized, and leading/trailing hyphens are removed.
• add: to_pascal_case Converts words separated by space, underscore, or hyphen to PascalCase. Each word is capitalized. Handles all-uppercase words and removes leading/trailing separators.
• add: to_snake_case Converts a string to snake_case. Uppercase ASCII letters are converted to lowercase. Word boundaries are detected and replaced with a single underscore. Multiple separators are normalized, and leading/trailing underscores are removed.

[v0.1.0] - 2025-06-27

• add: contains Checks if a substring is present in the string. Operates on bytes, not code points.
• add: has_prefix Checks if the string starts with the given prefix. Operates on bytes, not code points.
• add: has_suffix Checks if the string ends with the given suffix. Operates on bytes, not code points.
• add: contains_any Checks if any Unicode code point in the given set is present in the string. Unicode-aware.
• add: count_substring Counts the number of non-overlapping occurrences of a substring in the string. Operates on bytes, not code points.
• add: equal_fold Checks if two strings are equal, ignoring ASCII case. (Full Unicode case folding not yet supported.)
• add: fields Splits a string by runs of Unicode whitespace, returning a list of substrings. Returns an empty list if only whitespace.
• add: fields_func Splits a string at runs of Unicode code points where the given predicate returns true, returning a list of substrings.
• add: index Returns the byte offset of the first occurrence of a substring in the string, or -1 if not found.
• add: repeat Returns a new string consisting of the given string repeated a specified number of times. Raises an exception if the count is negative.
• add: join Concatenates a list of strings, inserting the given separator between each element. Returns the empty string if the list is empty.
