Enum TextOp 

pub enum TextOp {
    Insert {
        offset: u64,
        content: String,
    },
    Delete {
        offset: u64,
        content: String,
    },
}

A single text edit. Atoms hold an ordered list of these.

Delete carries the bytes it removes so the inverse operation (Insert of the same content at the same offset) reconstructs the pre-image without consulting the document.

Variants

Insert

Insert content at byte offset.

Fields

offset: u64

content: String

Delete

Delete content at byte offset. content is the removed bytes.

Fields

offset: u64

content: String

Implementations

impl TextOp

pub fn invert(&self) -> TextOp

Return the constructive inverse: Insert ↔ Delete with the same offset and content.

pub fn apply(&self, document: &mut Vec<u8>) -> Result<(), AtomError>

Apply this op to document (as a UTF-8 byte buffer). Returns an error if the offset is out of range or if a Delete’s recorded content does not match what is in the document at that offset.

Trait Implementations

impl Clone for TextOp

fn clone(&self) -> TextOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TextOp

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TextOp

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TextOp

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for TextOp

impl StructuralPartialEq for TextOp
