Struct automerge::Cursor

pub struct Cursor { /* private fields */ }

An identifier of a position in a Sequence (either Self::List or Self::Text).

Every element in an Automerge Sequence can be internally identified with an operation ID. While ExId is our default external representation of the Operation ID, it can be quite heavy. Therefore, we use this lightweight specialized structure.

This can be persisted using to_bytes and TryFrom<&u8>.

A cursor is obtained from ReadDoc::get_cursor and dereferenced with ReadDoc::get_cursor_position.

Implementations

impl Cursor

pub fn to_bytes(&self) -> Vec<u8>

Trait Implementations

impl Clone for Cursor

fn clone(&self) -> Cursor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Cursor

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

Formats the value using the given formatter.

impl Display for Cursor

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

Formats the value using the given formatter.

impl PartialEq<Cursor> for Cursor

fn eq(&self, other: &Cursor) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> TryFrom<&'a [u8]> for Cursor

type Error = AutomergeError

The type returned in the event of a conversion error.

fn try_from(value: &'a [u8]) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<&str> for Cursor

type Error = AutomergeError

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<String> for Cursor

type Error = AutomergeError

The type returned in the event of a conversion error.

fn try_from(s: String) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Vec<u8, Global>> for Cursor

type Error = AutomergeError

The type returned in the event of a conversion error.

fn try_from(value: Vec<u8>) -> Result<Self, Self::Error>

Performs the conversion.
