A filter definition

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct {{ .. }} syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

event_fields: Option<&'a [String]>

List of event fields to include.

If this list is absent then all fields are included. The entries may include ‘.’ characters to indicate sub-fields. So [‘content.body’] will include the ‘body’ field of the ‘content’ object. A literal ‘.’ character in a field name may be escaped using a ’'. A server may include more fields than were requested.

event_format: EventFormat

The format to use for events.

‘client’ will return the events in a format suitable for clients. ‘federation’ will return the raw event as received over federation. The default is ‘client’.

presence: Filter<'a>

The presence updates to include.

account_data: Filter<'a>

The user account data that isn’t associated with rooms to include.

room: RoomFilter<'a>

Filters to be applied to room data.

Implementations

impl<'a> FilterDefinition<'a>

pub fn empty() -> Self

Creates an empty FilterDefinition.

You can also use the Default implementation.

pub fn ignore_all() -> Self

Creates a new FilterDefinition that can be used to ignore all events.

pub fn is_empty(&self) -> bool

Returns true if all fields are empty.

Trait Implementations

fn from(def: FilterDefinition<'a>) -> Self

Performs the conversion.

impl<'a> Outgoing for FilterDefinition<'a>

type Incoming = IncomingFilterDefinition
