Struct Change 

pub struct Change<'s, S = &'s str> { /* private fields */ }

A change in a buffer, with a start, taken text, and added text

Implementations

impl Change<'static, String>

pub fn new(edit: impl ToString, range: Range<Point>, text: &Text) -> Self

Returns a new Change.

pub fn as_ref(&self) -> Change<'_, &str>

Returns a copyable Change

pub fn try_merge(&mut self, older: Self)

In this function, it is assumed that self happened after newer

If the merger fails, the older Change will be returned;

impl<'a> Change<'a>

pub fn to_string_change(&self) -> Change<'static, String>

Creates a Change<String> from a Change<&str>

pub fn str_insert(added_str: &'a str, start: Point) -> Self

Returns a new copyable Change from an insertion.

impl<'s, S: Borrow<str>> Change<'s, S>

pub fn reverse(self) -> Self

Returns a reversed version of this Change

pub fn line_range(&self, bytes: &Bytes) -> Range<Point>

Gets a Range<Point>, from the start to the end of the affected lines

For example, if you make an edit that transforms lines 1..=3 to lines 1..=5, this function will return a Range that starts at the beginning of line 1, and ends at the end of line 5.

[!NOTE]

This end of this range will come after the last \n, which means that, in that example, said point would have a Point::line value equal to 6, not 5, since it represents both the end of line 5, and the beginning of line 6.

pub fn start(&self) -> Point

The Point at the start of the change

pub fn taken_end(&self) -> Point

Returns the end of the Change, before it was applied

pub fn added_end(&self) -> Point

Returns the end of the Change, after it was applied

pub fn taken_range(&self) -> Range<Point>

Returns the taken Range

pub fn added_range(&self) -> Range<Point>

Returns the added Range

pub fn added_str(&self) -> &str

The text that was taken on this Change

pub fn taken_str(&self) -> &str

The text that was added by this Change

pub fn shift(&self) -> [i32; 3]

The total shift caused by this Change

Trait Implementations

impl<'de, Context> BorrowDecode<'de, Context> for Change<'static, String>

fn borrow_decode<D: BorrowDecoder<'de, Context = Context>>( decoder: &mut D, ) -> Result<Self, DecodeError>

Attempt to decode this type with the given BorrowDecode.

impl<'s, S: Clone> Clone for Change<'s, S>

fn clone(&self) -> Change<'s, S>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'s, S: Debug> Debug for Change<'s, S>

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

Formats the value using the given formatter.

impl<Context> Decode<Context> for Change<'static, String>

fn decode<D: Decoder<Context = Context>>( decoder: &mut D, ) -> Result<Self, DecodeError>

Attempt to decode this type with the given Decode.

impl<'s, S: Default> Default for Change<'s, S>

fn default() -> Change<'s, S>

Returns the “default value” for a type.

impl Encode for Change<'static, String>

fn encode<E: Encoder>(&self, encoder: &mut E) -> Result<(), EncodeError>

Encode a given type.

impl<'s, S: Ord> Ord for Change<'s, S>

fn cmp(&self, other: &Change<'s, S>) -> 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<'s, S: PartialEq> PartialEq for Change<'s, S>

fn eq(&self, other: &Change<'s, S>) -> 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<'s, S: PartialOrd> PartialOrd for Change<'s, S>

fn partial_cmp(&self, other: &Change<'s, S>) -> 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.
