Trait Text

pub trait Text {
    // Required methods
    fn line(&self, number: usize) -> Option<&Self>;
    fn length(&self) -> usize;
    fn line_count(&self) -> usize;
    fn character(&self, idx: usize) -> Option<char>;
    fn len_before_line(&self, line: usize) -> usize;
}

This contains the information about the text that is used by the cursor to handle navigation.

Required Methods

fn line(&self, number: usize) -> Option<&Self>

Returns the line at the given index.

fn length(&self) -> usize

Returns the length of the text in characters.

fn line_count(&self) -> usize

Returns the number of lines in the text.

fn character(&self, idx: usize) -> Option<char>

Returns the character at the given character index.

fn len_before_line(&self, line: usize) -> usize

Returns the length of the text before the given line in characters.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
