Modules

allocation

arena

awareness

change

Changes are merged ops.

configure

container

CRDT [Container]. Each container may have different CRDT type ContainerType. Each [Op] has an associated container. It’s the [Container]’s responsibility to calculate the state from the [Op]s.

cursor

dag

DAG (Directed Acyclic Graph) is a common data structure in distributed system.

Macros

array_mut_ref

loro_value

A macro for creating LoroValue. It works just like the json! macro in serde_json.

Structs

ChangeMeta

Change is a grouped continuous operations that share the same id, timestamp, commit message.

CounterSpan

This struct supports reverse repr: from can be less than to. We need this because it’ll make merging deletions easier.

DocState

FractionalIndex

ID

It’s the unique ID of an Op represented by PeerID and Counter.

IdLp

It’s the unique ID of an Op represented by PeerID and Lamport clock. It’s used to define the total order of Ops.

IdSpan

This struct supports reverse repr: CounterSpan’s from can be less than to. But we should use it conservatively. We need this because it’ll make merging deletions easier.

LoroBinaryValue

LoroDoc

LoroDoc serves as the library’s primary entry point. It’s constituted by an OpLog and an DocState.

LoroDocInner

LoroListValue

LoroMapValue

LoroStringValue

StringSlice

Subscription

A handle to a subscription created by GPUI. When dropped, the subscription is cancelled and the callback will no longer be invoked.

TreeID

Each node of movable tree has a unique TreeID generated by Loro.

TreeNode

TreeNodeWithChildren

Enums

ContainerType

LoroEncodeError

LoroError

LoroTreeError

LoroValue

LoroValue is used to represents the state of CRDT at a given version.

TreeParentId

Constants

LORO_VERSION

The version of the loro crate

Traits

ApplyDiff

ToJson

Functions

to_value

Type Aliases

Counter

If it’s the nth Op of a peer, the counter will be n.

FxHashMap

A HashMap using a default Fx hasher.

IdSpanVector

Lamport

It’s the Lamport clock

LoroResult

PeerID

Unique id for each peer. It’s a random u64 by default.
