CommandRetentionConfig

arminius_lib_nats::config

Struct CommandRetentionConfig 

Source 
pub struct CommandRetentionConfig {
    pub max_age: Option<Duration>,
    pub max_messages: Option<i64>,
    pub max_bytes: Option<i64>,
}
Expand description

Retention limits for command request-reply streams.

The retention policy is fixed to WorkQueue and cannot be configured: command dispatch relies on WorkQueue semantics (each command delivered to exactly one responder and removed on ack). Only these limits are tunable; None means unlimited.

Fields§

§max_age: Option<Duration>

Drop messages older than this age (None = unlimited).

§max_messages: Option<i64>

Drop oldest messages when count exceeds this (None = unlimited).

§max_bytes: Option<i64>

Drop oldest messages when total bytes exceeds this (None = unlimited).

Implementations§

Source§

impl CommandRetentionConfig

Source

pub(crate) fn build_stream_config( &self, name: String, subjects: Vec<String>, ) -> Config

Builds a WorkQueue [nats_stream::Config] for a command stream from these limits. The policy is always WorkQueue by construction.
