Struct TextOperation 

pub struct TextOperation { /* private fields */ }

A text operation consisting of multiple atomic operations

Implementations

impl TextOperation

pub fn new() -> Self

Creates a new empty text operation

pub fn with_base_length(base_length: usize) -> Self

Creates a text operation from a base length

Arguments

• base_length - The length of the document before this operation

pub fn retain(&mut self, n: usize) -> &mut Self

Adds a retain operation

Arguments

• n - Number of characters to retain

pub fn insert(&mut self, text: String) -> &mut Self

Adds an insert operation

Arguments

• text - Text to insert

pub fn delete(&mut self, n: usize) -> &mut Self

Adds a delete operation

Arguments

• n - Number of characters to delete

pub fn apply(&self, text: &str) -> SyncResult<String>

Applies this operation to a string

Arguments

• text - The text to apply the operation to

Returns

The resulting text after applying the operation

pub fn base_length(&self) -> usize

Gets the base length

pub fn target_length(&self) -> usize

Gets the target length

pub fn operations(&self) -> &[Operation]

Gets the operations

pub fn is_noop(&self) -> bool

Checks if the operation is a no-op

Trait Implementations

impl Clone for TextOperation

fn clone(&self) -> TextOperation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TextOperation

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

Formats the value using the given formatter.

impl Default for TextOperation

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TextOperation

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TextOperation

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Transform for TextOperation

fn transform(&self, other: &Self) -> SyncResult<Self>

Transforms this operation against another concurrent operation

fn compose(&self, other: &Self) -> SyncResult<Self>

Composes this operation with another sequential operation

fn invert(&self) -> SyncResult<Self>

Inverts this operation

impl Eq for TextOperation
