pub struct Str { /* private fields */ }

Implementations

impl Str

pub fn new() -> Self

Creates a new empty Str.

pub fn len(&self) -> i32

Returns the length of this Str, in bytes.

pub fn is_empty(&self) -> bool

Returns true if this Str has a length of 0, and false otherwise.

pub fn chars(&self) -> Chars<'_>

Returns an iterator over the chars of a string.

pub fn char_at(&self, index: i32) -> Option<char>

Extracts the ith character of the string. Index can be negative, like Python’s str: str[-1] gets the last element.

pub fn find(&self, pattern: &str) -> Option<usize>

Returns the byte index of the first character of this string that matches the pattern.

pub fn contains(&self, pattern: &str) -> bool

Returns true if the given pattern matches a sub-slice of this string.

pub fn count(&self, element: char) -> usize

Count the total number of occurrences of the specified element in the string.

pub fn to_decimal(&self) -> Option<f64>

Convert the string to a double-precision floating-point decimal number.

pub fn starts_with(&self, pattern: &str) -> bool

Return true if the string starts with the specified string, otherwise return false.

pub fn ends_with(&self, pattern: &str) -> bool

Return true if the string ends with the specified string, otherwise return false.

pub fn lower(&self) -> Self

Returns the lowercase equivalent of this string, as a new Str.

pub fn upper(&self) -> Self

Returns the uppercase equivalent of this string, as a new Str.

pub fn replace(&self, old_str: &str, new_str: &str) -> Self

Replaces all matches of a pattern with another string.

pub fn strip(&self) -> Self

Returns a string with leading and trailing whitespace removed.

pub fn split(&self, separator: &str) -> List<&str>

Split string with separator.

pub fn join(&self, str_list: List<&str>) -> Self

Return a string which is the concatenation of the strings in str_list.
