Required Associated Types

type Underlying: Clone + PartialEq

Required Methods

fn get_range(&self, range: Range<usize>) -> &[Self::Underlying]

fn decode_str(src: &str) -> Cow<'_, [Self::Underlying]>

Used for string replacement. We need this for indentation and deindentation.

fn encode_bytes(bytes: &[Self::Underlying]) -> Cow<'_, str>

Used for string replacement. We need this for transformation.

fn get_char_column(&self, column: usize, offset: usize) -> usize

Get the character column at the given position

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.

Implementations on Foreign Types

impl Content for String

fn get_char_column(&self, _col: usize, offset: usize) -> usize

This is an O(n) operation. We assume the col will not be a huge number in reality. This may be problematic for special files like compressed js

type Underlying = u8

fn get_range(&self, range: Range<usize>) -> &[Self::Underlying]

fn decode_str(src: &str) -> Cow<'_, [Self::Underlying]>

fn encode_bytes(bytes: &[Self::Underlying]) -> Cow<'_, str>
