Struct TextWidth

pub struct TextWidth(/* private fields */);

Byte length of an utf8 string.

Implementations

impl TextWidth

pub const ZERO: Self

pub fn from_char(c: char) -> Self

pub fn from_str(s: &str) -> Self

pub fn new_for_testing(value: u32) -> Self

pub fn at(s: &str, index: usize) -> Self

Creates a TextWidth at the given index of a string.

The index is required to be a char boundary. This function runs a debug assertion to verify this, while retains performance on release builds.

pub fn as_u32(self) -> u32

pub fn as_offset(self) -> TextOffset

Trait Implementations

impl Add for TextWidth

type Output = TextWidth

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl Clone for TextWidth

fn clone(&self) -> TextWidth

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TextWidth

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

Formats the value using the given formatter.

impl Default for TextWidth

fn default() -> TextWidth

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TextWidth

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for TextWidth

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for TextWidth

fn cmp(&self, other: &TextWidth) -> 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.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for TextWidth

fn eq(&self, other: &TextWidth) -> 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 PartialOrd for TextWidth

fn partial_cmp(&self, other: &TextWidth) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for TextWidth

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Sub for TextWidth

type Output = TextWidth

The resulting type after applying the - operator.

fn sub(self, rhs: Self) -> Self::Output

Performs the - operation.

impl Sum for TextWidth

fn sum<I: Iterator<Item = Self>>(iter: I) -> Self

Takes an iterator and generates Self from the elements by “summing up” the items.

impl Copy for TextWidth

impl Eq for TextWidth

impl StructuralPartialEq for TextWidth
