Implementations
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

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.
Methods from Deref<Target = JsValue>
pub const NULL: JsValue
[src]
pub const UNDEFINED: JsValue
[src]
pub const TRUE: JsValue
[src]
pub const FALSE: JsValue
[src]
pub fn into_serde<T>(&self) -> Result<T, Error> where
T: for<'a> Deserialize<'a>,
[src]
T: for<'a> Deserialize<'a>,
Invokes JSON.stringify
on this value and then parses the resulting
JSON into an arbitrary Rust value.
This function will first call JSON.stringify
on the JsValue
itself.
The resulting string is then passed into Rust which then parses it as
JSON into the resulting value.
Usage of this API requires activating the serde-serialize
feature of
the wasm-bindgen
crate.
Errors
Returns any error encountered when parsing the JSON into a T
.
pub fn as_f64(&self) -> Option<f64>
[src]
Returns the f64
value of this JS value if it's an instance of a
number.
If this JS value is not an instance of a number then this returns
None
.
pub fn is_string(&self) -> bool
[src]
Tests whether this JS value is a JS string.
pub fn as_string(&self) -> Option<String>
[src]
If this JS value is a string value, this function copies the JS string
value into wasm linear memory, encoded as UTF-8, and returns it as a
Rust String
.
To avoid the copying and re-encoding, consider the
JsString::try_from()
function from js-sys
instead.
If this JS value is not an instance of a string or if it's not valid
utf-8 then this returns None
.
UTF-16 vs UTF-8
JavaScript strings in general are encoded as UTF-16, but Rust strings
are encoded as UTF-8. This can cause the Rust string to look a bit
different than the JS string sometimes. For more details see the
documentation about the str
type which contains a few
caveats about the encodings.
pub fn as_bool(&self) -> Option<bool>
[src]
Returns the bool
value of this JS value if it's an instance of a
boolean.
If this JS value is not an instance of a boolean then this returns
None
.
pub fn is_null(&self) -> bool
[src]
Tests whether this JS value is null
pub fn is_undefined(&self) -> bool
[src]
Tests whether this JS value is undefined
pub fn is_symbol(&self) -> bool
[src]
Tests whether the type of this JS value is symbol
pub fn is_object(&self) -> bool
[src]
Tests whether typeof self == "object" && self !== null
.
pub fn is_function(&self) -> bool
[src]
Tests whether the type of this JS value is function
.
pub fn is_truthy(&self) -> bool
[src]
Tests whether the value is "truthy".
pub fn is_falsy(&self) -> bool
[src]
Tests whether the value is "falsy".
