Struct zng::text::CaretStatus

pub struct CaretStatus { /* private fields */ }

Display info of edit caret position.

Implementations

impl CaretStatus

pub fn none() -> CaretStatus

Status for text without caret.

pub fn new(index: usize, text: &SegmentedText) -> CaretStatus

New position from char index and text.

Panics

Panics if index is greater then text length.

pub fn index(&self) -> Option<usize>

Char index on the text string, starts a 0, can be the length of the text.

pub fn line(&self) -> Option<NonZero<u32>>

Display line, starts at 1.

Note that this does not count soft line breaks (wrapped lines), this is the actual text line.

pub fn column(&self) -> Option<NonZero<u32>>

Display column, starts at 1.

This is the char count from the start of the text line to the index.

Trait Implementations

impl Clone for CaretStatus

fn clone(&self) -> CaretStatus

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CaretStatus

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CaretStatus

fn deserialize<__D>( __deserializer: __D, ) -> Result<CaretStatus, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CaretStatus

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

Formats the value using the given formatter.

impl Hash for CaretStatus

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

where __H: Hasher,

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 PartialEq for CaretStatus

fn eq(&self, other: &CaretStatus) -> 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 CaretStatus

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
