Structs
Iterator structure used by shared array data type.
Iterator structure used by XML nodes (elements and text) to iterate over node’s attributes.
Attribute iterators are unordered - there’s no specific order in which map entries will be
returned during consecutive iterator calls.
Iterator structure used by shared map data type. Map iterators are unordered - there’s no
specific order in which map entries will be returned during consecutive iterator calls.
Transaction is one of the core types in Yrs. All operations that need to touch or
modify a document’s contents (a.k.a. block store), need to be executed in scope of a
transaction.
Iterator used to traverse over the complex nested tree structure of a XML node. XML node
iterator walks only over
YXmlElement and YXmlText nodes. It does so in ordered manner (using
the order in which children are ordered within their parent nodes) and using depth-first
traverse.Event generated for callbacks subscribed using
ydoc_observe_after_transaction. It contains
snapshot of changes made within any committed transaction.Event pushed into callbacks registered with
yarray_observe function. It contains delta of all
content changes made within a scope of corresponding transaction (see: yarray_event_delta) as
well as navigation data used to identify a YArray instance which triggered this event.Delete set is a map of
(ClientID, Range[]) entries. Length of a map is stored in
entries_count field. ClientIDs reside under client_ids and their corresponding range
sequences can be found under the same index of ranges field.A data type representing a single change detected over an observed
YText/YXmlText. A type
of change can be detected using a tag field:A single instance of formatting attribute stored as part of
YDelta instance.A data type representing a single change detected over an observed shared collection. A type
of change can be detected using a
tag field:A data type representing a single change made over a map component of shared collection types,
such as
YMap entries or YXmlText/YXmlElement attributes. A key field provides a
corresponding unique key string of a changed entry, while tag field informs about specific
type of change being done:Fixed-length sequence of ID ranges. Each range is a pair of [start, end) values, describing the
range of items identified by clock values, that this range refers to.
A data structure that is used to pass input values of various types supported by Yrs into a
shared document store.
A structure representing single key-value entry of a map output (used by either
embedded JSON-like maps or YMaps).
Event pushed into callbacks registered with
ymap_observe function. It contains all
key-value changes made within a scope of corresponding transaction (see: ymap_event_keys) as
well as navigation data used to identify a YMap instance which triggered this event.Configuration object used by
YDoc.An output value cell returned from yrs API methods. It describes a various types of data
supported by yrs shared data types.
A single segment of a path returned from
yevent_path function. It can be one of two cases,
recognized by it’s tag field:Struct representing a state of a document. It contains the last seen clocks for blocks submitted
per any of the clients collaborating on document updates.
A sticky index is based on the Yjs model and is not affected by document changes.
E.g. If you place a sticky index before a certain character, it will always point to this character.
If you place a sticky index at the end of a type, it will always point to the end of the type.
Event pushed into callbacks registered with
ytext_observe function. It contains delta of all
text changes made within a scope of corresponding transaction (see: ytext_event_delta) as
well as navigation data used to identify a YText instance which triggered this event.A structure representing single attribute of an either
YXmlElement or YXmlText instance.
It consists of attribute name and string, both of which are null-terminated UTF-8 strings.Event pushed into callbacks registered with
yxmlelem_observe function. It contains
all attribute changes made within a scope of corresponding transaction
(see: yxmlelem_event_keys) as well as child XML nodes changes (see: yxmlelem_event_delta)
and navigation data used to identify a YXmlElement instance which triggered this event.Event pushed into callbacks registered with
yxmltext_observe function. It contains
all attribute changes made within a scope of corresponding transaction
(see: yxmltext_event_keys) as well as text edits (see: yxmltext_event_delta)
and navigation data used to identify a YXmlText instance which triggered this event.Constants

A common shared data type. All Yrs instances can be refered to using this data type (use
ytype_kind function if a specific type needs to be determined). Branch pointers are passed
over type-specific functions like ytext_insert, yarray_insert or ymap_insert to perform
a specific shared type operations.A Yrs document type. Documents are most important units of collaborative resources management.
All shared collections live within a scope of their corresponding documents. All updates are
generated on per document basis (rather than individual shared type). All operations on shared
collections happen via
YTransaction, which lifetime is also bound to a document.
