Struct Value

pub struct Value { /* private fields */ }

The value of a TextInput.

Implementations

impl Value

pub fn new(string: &str) -> Self

Creates a new Value from a string slice.

pub fn is_empty(&self) -> bool

Returns whether the Value is empty or not.

A Value is empty when it contains no graphemes.

pub fn len(&self) -> usize

Returns the total amount of graphemes in the Value.

pub fn previous_start_of_word(&self, index: usize) -> usize

Returns the position of the previous start of a word from the given grapheme index.

pub fn next_end_of_word(&self, index: usize) -> usize

Returns the position of the next end of a word from the given grapheme index.

pub fn select(&self, start: usize, end: usize) -> Self

Returns a new Value containing the graphemes from start until the given end.

pub fn until(&self, index: usize) -> Self

Returns a new Value containing the graphemes until the given index.

pub fn insert(&mut self, index: usize, c: char)

Inserts a new char at the given grapheme index.

pub fn insert_many(&mut self, index: usize, value: Value)

Inserts a bunch of graphemes at the given grapheme index.

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

Removes the grapheme at the given index.

pub fn remove_many(&mut self, start: usize, end: usize)

Removes the graphemes from start to end.

pub fn secure(&self) -> Self

Returns a new Value with all its graphemes replaced with the dot (‘•’) character.

pub fn byte_index_at_grapheme(&self, grapheme_index: usize) -> usize

Converts a grapheme index to a byte index in the underlying string.

pub fn rfind_char(&self, ch: char) -> Option<usize>

Returns the grapheme index of the last occurrence of the given character, searching from the end.

pub fn grapheme_index_at_byte(&self, byte_index: usize) -> usize

Converts a byte index to a grapheme index.

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl Default for Value

fn default() -> Value

Returns the “default value” for a type.

impl Display for Value

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

Formats the value using the given formatter.

impl PartialEq for Value

fn eq(&self, other: &Value) -> 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.
