Struct String16

pub struct String16 { /* private fields */ }

A UTF-16 encoded, growable string.

Examples

let mut string16 = String16::from(“Übung”); string16.push(‘ä’);

Implementations

impl String16

pub fn new() -> Self

Creates a new empty String16.

pub fn len(&self) -> usize

Returns the length of this String16, in bytes.

Examples

Basic usage:

let a = String16::from(“Übung”);

assert_eq!(a.len(), 5);

pub fn as_bytes(&self) -> &[u16]

Returns a slice of u16s bytes that were attempted to convert to a String.

pub fn as_bytes_mut(&mut self) -> &mut [u16]

Returns a mutable slice of u16s bytes that were attempted to convert to a String.

pub fn insert_str(&mut self, idx: usize, string: &str)

Inserts a string slice into this String16 at a byte position.

pub fn push(&mut self, ch: char)

Appends a given char onto the end of this String16.

pub fn remove(&mut self, idx: usize)

Removes a char from this String16 at a byte position and returns it.

pub fn is_empty(&self) -> bool

Returns true if this String16 has a length of zero, and false otherwise.

pub fn ends_with(&self, pat: &str) -> bool

Returns true if this String16 ends with the given string slice, or false otherwise.

pub fn clear(&mut self)

Truncates this String16, removing all contents.

pub fn get_string(&self, start: usize, end: usize) -> Option<String>

Returns a string part begins with the startand ends with the end index.

pub fn as_string(&self) -> String

Converts the String16 value to a String.

Trait Implementations

impl Clone for String16

fn clone(&self) -> String16

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for String16

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for String16

fn default() -> String16

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for String16

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for String16

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<&str> for String16

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<String> for String16

fn from(string: String) -> Self

Converts to this type from the input type.

impl PartialEq for String16

fn eq(&self, other: &String16) -> bool

Tests for self and other values to be equal, and is used by ==.

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 Serialize for String16

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
