[−][src]Struct eventstore::types::StreamMetadata
Represents stream metadata with strongly types properties for system values and a dictionary-like interface for custom values.
Fields
max_count: Option<u64>
A sliding window based on the number of items in the stream. When data reaches a certain length it disappears automatically from the stream and is considered eligible for scavenging.
max_age: Option<Duration>
A sliding window based on dates. When data reaches a certain age it disappears automatically from the stream and is considered eligible for scavenging.
truncate_before: Option<u64>
The event number from which previous events can be scavenged. This is used to implement soft-deletion of streams.
cache_control: Option<Duration>
Controls the cache of the head of a stream. Most URIs in a stream are infinitely cacheable but the head by default will not cache. It may be preferable in some situations to set a small amount of caching on the head to allow intermediaries to handle polls (say 10 seconds).
acl: StreamAcl
The access control list for the stream.
custom_properties: HashMap<String, Value>
An enumerable of key-value pairs of keys to JSON value for user-provided metadata.
