Struct JsStr

pub struct JsStr<'a> { /* private fields */ }

This is equivalent to Rust’s &str.

Implementations

impl<'a> JsStr<'a>

pub const EMPTY: Self

This represents an empty string.

pub const fn latin1(value: &'a [u8]) -> Self

Creates a JsStr from codepoints that can fit in a u8.

pub const fn utf16(value: &'a [u16]) -> Self

Creates a JsStr from utf16 encoded string.

pub const fn len(&self) -> usize

Get the length of the JsStr.

pub const fn variant(self) -> JsStrVariant<'a>

Return the inner JsStrVariant varient of the JsStr.

pub const fn is_latin1(&self) -> bool

Check if the JsStr is latin1 encoded.

pub const fn as_latin1(&self) -> Option<&[u8]>

Returns u8 slice if the JsStr is latin1 encoded, otherwise None.

pub fn iter(self) -> Iter<'a>

Iterate over the codepoints of the string.

pub fn windows(self, size: usize) -> Windows<'a>

Iterate over the codepoints of the string.

pub fn is_empty(&self) -> bool

Check if the JsStr is empty.

pub fn trim(self) -> JsStr<'a>

Trims both leading and trailing space.

pub fn trim_start(self) -> Self

Trims all leading space.

pub fn trim_end(self) -> Self

Trims all trailing space.

pub fn get<I>(self, index: I) -> Option<I::Value>

where I: JsSliceIndex<'a>,

Returns an element or subslice depending on the type of index, otherwise None.

pub unsafe fn get_unchecked<I>(self, index: I) -> I::Value

where I: JsSliceIndex<'a>,

Returns an element or subslice depending on the type of index, without doing bounds check.

Safety

Caller must ensure the index is not out of bounds

pub fn to_vec(&self) -> Vec<u16>

Convert the JsStr into a Vec<U16>.

pub fn starts_with(&self, needle: JsStr<'_>) -> bool

Returns true if needle is a prefix of the JsStr.

pub fn ends_with(&self, needle: JsStr<'_>) -> bool

Returns true if needle is a suffix of the JsStr.

Trait Implementations

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Ord for JsStr<'_>

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.
