Struct Change

pub struct Change<S: AsRef<str>> { /* private fields */ }

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

Implementations

impl Change<String>

pub fn new(edit: impl ToString, [p0, p1]: [Point; 2], 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 str>

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

Returns a new copyable Change from an insertion.

impl<S: AsRef<str>> Change<S>

pub fn reverse(self) -> Change<S>

Returns a reversed version of this Change

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<usize>

Returns the taken Range

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

Returns the added Range

pub fn added_text(&self) -> &str

The text that was taken on this Change

pub fn taken_text(&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, S, __Context> BorrowDecode<'__de, __Context> for Change<S>

where S: BorrowDecode<'__de, __Context> + AsRef<str>,

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: Clone + AsRef<str>> Clone for Change<S>

fn clone(&self) -> Change<S>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S: Debug + AsRef<str>> Debug for Change<S>

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

Formats the value using the given formatter.

impl<S, __Context> Decode<__Context> for Change<S>

where S: Decode<__Context> + AsRef<str>,

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

Attempt to decode this type with the given Decode.

impl<S: Default + AsRef<str>> Default for Change<S>

fn default() -> Change<S>

Returns the “default value” for a type.

impl<S> Encode for Change<S>

where S: Encode + AsRef<str>,

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

Encode a given type.

impl<S: Ord + AsRef<str>> Ord for Change<S>

fn cmp(&self, other: &Change<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: PartialEq + AsRef<str>> PartialEq for Change<S>

fn eq(&self, other: &Change<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: PartialOrd + AsRef<str>> PartialOrd for Change<S>

fn partial_cmp(&self, other: &Change<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.
