Implementations§

source§

impl JsString

source

pub fn length(&self) -> u32

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

MDN documentation

source§

impl JsString

source

pub fn at(&self, index: i32) -> Option<JsString>

The ‘at()’ method returns a new string consisting of the single UTF-16 code unit located at the specified offset into the string, counting from the end if it’s negative.

MDN documentation

source§

impl JsString

source

pub fn char_at(&self, index: u32) -> JsString

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

source§

impl JsString

source

pub fn char_code_at(&self, index: u32) -> f64

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.

source§

impl JsString

source

pub fn from_char_code(char_codes: &[u16]) -> JsString

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.

Additionally, this function accepts u16 for character codes, but fixing others requires a breaking change release (see https://github.com/rustwasm/wasm-bindgen/issues/1460 for details).

impl JsString

source

pub fn try_from(val: &JsValue) -> Option<&JsString>

👎Deprecated: recommended to use dyn_ref instead which is now equivalent

Returns the JsString value of this JS value if it’s an instance of a string.

If this JS value is not an instance of a string then this returns None.

source

pub fn is_valid_utf16(&self) -> bool

Returns whether this string is a valid UTF-16 string.

This is useful for learning whether String::from(..) will return a lossless representation of the JS string. If this string contains unpaired surrogates then String::from will succeed but it will be a lossy representation of the JS string because unpaired surrogates will become replacement characters.

If this function returns false then to get a lossless representation of the string you’ll need to manually use the iter method (or the char_code_at accessor) to view the raw character codes.

For more information, see the documentation on JS strings vs Rust strings

source

pub fn iter(&self) -> impl ExactSizeIterator + DoubleEndedIterator

Returns an iterator over the u16 character codes that make up this JS string.

This method will call char_code_at for each code in this JS string, returning an iterator of the codes in sequence.

source

pub fn as_char(&self) -> Option<char>

If this string consists of a single Unicode code point, then this method converts it into a Rust char without doing any allocations.

If this JS value is not a valid UTF-8 or consists of more than a single codepoint, then this returns None.

Note that a single Unicode code point might be represented as more than one code unit on the JavaScript side. For example, a JavaScript string "\uD801\uDC37" is actually a single Unicode code point U+10437 which corresponds to a character ‘𐐷’.

Methods from Deref<Target = Object>§

source

pub fn as_f64(&self) -> Option<f64>

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.

source

pub fn is_string(&self) -> bool

Tests whether this JS value is a JS string.

source

pub fn as_string(&self) -> Option<String>

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.

fn eq(&self, other: &&'a str) -> bool

Tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl RefFromWasmAbi for JsString

source§

type Abi = <JsValue as RefFromWasmAbi>::Abi

The Wasm ABI type references to Self are recovered from.
source§

type Anchor = ManuallyDrop<JsString>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.
source§
