Methods

impl JsString
[src]

The length property of a String object indicates the length of a string, in UTF-16 code units.

MDN documentation

impl JsString
[src]

The String object's charAt() method returns a new string consisting of the single UTF-16 code unit located at the specified offset into the string.

MDN documentation

impl JsString
[src]

The charCodeAt() method returns an integer between 0 and 65535 representing the UTF-16 code unit at the given index (the UTF-16 code unit matches the Unicode code point for code points representable in a single UTF-16 code unit, but might also be the first code unit of a surrogate pair for code points not representable in a single UTF-16 code unit, e.g. Unicode code points > 0x10000). If you want the entire code point value, use codePointAt().

Returns NaN if index is out of range.

MDN documentation

impl JsString
[src]

The codePointAt() method returns a non-negative integer that is the Unicode code point value.

MDN documentation

impl JsString
[src]

The concat() method concatenates the string arguments to the calling string and returns a new string.

MDN documentation

impl JsString
[src]

The endsWith() method determines whether a string ends with the characters of a specified string, returning true or false as appropriate.

MDN documentation

impl JsString
[src]

The static String.fromCharCode() method returns a string created from the specified sequence of UTF-16 code units.

MDN documentation

Notes

There are a few bindings to from_char_code in js-sys: from_char_code1, from_char_code2, etc... with different arities.

Exceptions

A RangeError is thrown if an invalid Unicode code point is given

The includes() method determines whether one string may be found within another string, returning true or false as appropriate.

MDN documentation

impl JsString
[src]

The indexOf() method returns the index within the calling String object of the first occurrence of the specified value, starting the search at fromIndex. Returns -1 if the value is not found.

MDN documentation

impl JsString
[src]

The lastIndexOf() method returns the index within the calling String object of the last occurrence of the specified value, searching backwards from fromIndex. Returns -1 if the value is not found.

impl JsString
[src]

The localeCompare() method returns a number indicating whether a reference string comes before or after or is the same as the given string in sort order.

MDN documentation

impl JsString
[src]

The match() method retrieves the matches when matching a string against a regular expression.

MDN documentation

impl JsString
[src]

The normalize() method returns the Unicode Normalization Form of a given string (if the value isn't a string, it will be converted to one first).

MDN documentation

impl JsString
[src]

The padEnd() method pads the current string with a given string (repeated, if needed) so that the resulting string reaches a given length. The padding is applied from the end (right) of the current string.

MDN documentation

impl JsString
[src]

The padStart() method pads the current string with another string (repeated, if needed) so that the resulting string reaches the given length. The padding is applied from the start (left) of the current string.

MDN documentation

impl JsString
[src]

The repeat() method constructs and returns a new string which contains the specified number of copies of the string on which it was called, concatenated together.

MDN documentation

impl JsString
[src]

The replace() method returns a new string with some or all matches of a pattern replaced by a replacement. The pattern can be a string or a RegExp, and the replacement can be a string or a function to be called for each match.

Note: The original string will remain unchanged.

The search() method executes a search for a match between a regular expression and this String object.

impl JsString
[src]

The slice() method extracts a section of a string and returns it as a new string, without modifying the original string.

MDN documentation

impl JsString
[src]

The split() method splits a String object into an array of strings by separating the string into substrings, using a specified separator string to determine where to make each split.

The startsWith() method determines whether a string begins with the characters of a specified string, returning true or false as appropriate.

MDN documentation

impl JsString
[src]

The substring() method returns the part of the string between the start and end indexes, or to the end of the string.

MDN documentation

impl JsString
[src]

The substr() method returns the part of a string between the start index and a number of characters after it.

MDN documentation

impl JsString
[src]

The toLocaleLowerCase() method returns the calling string value converted to lower case, according to any locale-specific case mappings.

MDN documentation

impl JsString
[src]

The toLocaleUpperCase() method returns the calling string value converted to upper case, according to any locale-specific case mappings.

[src]

The toString() method returns a string representing the specified object.

[src]

The toUpperCase() method returns the calling string value converted to uppercase (the value will be converted to a string if it isn't one).

MDN documentation

impl JsString
[src]

The trim() method removes whitespace from both ends of a string. Whitespace in this context is all the whitespace characters (space, tab, no-break space, etc.) and all the line terminator characters (LF, CR, etc.).

MDN documentation

impl JsString
[src]

The trimEnd() method removes whitespace from the end of a string. trimRight() is an alias of this method.
