Methods
impl RegExp
[src]
pub fn exec(&self, text: &str) -> Option<Array>
[src]
The exec() method executes a search for a match in a specified string. Returns a result array, or null.
impl RegExp
[src]
pub fn flags(&self) -> JsString
[src]
The flags property returns a string consisting of the flags of the current regular expression object.
impl RegExp
[src]
pub fn global(&self) -> bool
[src]
The global property indicates whether or not the "g" flag is used with the regular expression. global is a read-only property of an individual regular expression instance.
impl RegExp
[src]
pub fn ignore_case(&self) -> bool
[src]
The ignoreCase property indicates whether or not the "i" flag is used with the regular expression. ignoreCase is a read-only property of an individual regular expression instance.
impl RegExp
[src]
pub fn input() -> JsString
[src]
The non-standard input property is a static property of regular expressions that contains the string against which a regular expression is matched. RegExp.$_ is an alias for this property.
impl RegExp
[src]
pub fn last_index(&self) -> u32
[src]
The lastIndex is a read/write integer property of regular expression instances that specifies the index at which to start the next match.
impl RegExp
[src]
pub fn set_last_index(&self, index: u32)
[src]
The lastIndex is a read/write integer property of regular expression instances that specifies the index at which to start the next match.
impl RegExp
[src]
pub fn last_match() -> JsString
[src]
The non-standard lastMatch property is a static and read-only property of regular expressions that contains the last matched characters. RegExp.$& is an alias for this property.
impl RegExp
[src]
pub fn last_paren() -> JsString
[src]
The non-standard lastParen property is a static and read-only property of regular expressions that contains the last parenthesized substring match, if any. RegExp.$+ is an alias for this property.
impl RegExp
[src]
pub fn left_context() -> JsString
[src]
The non-standard leftContext property is a static and read-only property of regular expressions that contains the substring preceding the most recent match. RegExp.$` is an alias for this property.
impl RegExp
[src]
pub fn multiline(&self) -> bool
[src]
The multiline property indicates whether or not the "m" flag is used with the regular expression. multiline is a read-only property of an individual regular expression instance.
impl RegExp
[src]
pub fn n1() -> JsString
[src]
The non-standard $1, $2, $3, $4, $5, $6, $7, $8, $9 properties are static and read-only properties of regular expressions that contain parenthesized substring matches.

pub fn new(pattern: &str, flags: &str) -> RegExp
[src]
The RegExp constructor creates a regular expression object for matching text with a pattern.
impl RegExp
[src]
pub fn new_regexp(pattern: &RegExp, flags: &str) -> RegExp
[src]
impl RegExp
[src]
pub fn right_context() -> JsString
[src]
The non-standard rightContext property is a static and read-only property of regular expressions that contains the substring following the most recent match. RegExp.$' is an alias for this property.
impl RegExp
[src]
pub fn source(&self) -> JsString
[src]
The source property returns a String containing the source text of the regexp object, and it doesn't contain the two forward slashes on both sides and any flags.
impl RegExp
[src]
pub fn sticky(&self) -> bool
[src]
The sticky property reflects whether or not the search is sticky (searches in strings only from the index indicated by the lastIndex property of this regular expression). sticky is a read-only property of an individual regular expression object.
impl RegExp
[src]
pub fn test(&self, text: &str) -> bool
[src]
The test() method executes a search for a match between a regular expression and a specified string. Returns true or false.
impl RegExp
[src]
pub fn to_string(&self) -> JsString
[src]
The toString() method returns a string representing the regular expression.
impl RegExp
[src]
pub fn unicode(&self) -> bool
[src]
The unicode property indicates whether or not the "u" flag is used with a regular expression. unicode is a read-only property of an individual regular expression instance.
Methods from Deref<Target = Object>
pub fn constructor(&self) -> Function
[src]
The constructor property returns a reference to the Object constructor function that created the instance object.
pub fn has_own_property(&self, property: &JsValue) -> bool
[src]
The hasOwnProperty()
method returns a boolean indicating whether the
object has the specified property as its own property (as opposed to
inheriting it).
pub fn is_prototype_of(&self, value: &JsValue) -> bool
[src]
The isPrototypeOf()
method checks if an object exists in another
object's prototype chain.
pub fn property_is_enumerable(&self, property: &JsValue) -> bool
[src]
The propertyIsEnumerable()
method returns a Boolean indicating
whether the specified property is enumerable.
pub fn to_locale_string(&self) -> JsString
[src]
The toLocaleString()
method returns a string representing the object.
This method is meant to be overridden by derived objects for
locale-specific purposes.
pub fn to_string(&self) -> JsString
[src]
The toString()
method returns a string representing the object.
pub fn value_of(&self) -> Object
[src]
The valueOf()
method returns the primitive value of the
specified object.
