Module context 

Per-delivery and per-batch context fields exposed to handlers.

A handler types its context parameter as Context<'_, StreamContext>, or binds one field as a parameter with the core’s Ctx<K> extractor and a key from keys.

• StreamContext: StreamContext, a stream delivery’s entry id, position, consumer group and seek handle, under keys::EntryId, keys::Position, keys::ConsumerGroup and keys::SeekHandle.
• ConsumerGroup: keys::ConsumerGroup, the group a stream subscription reads through.
• StreamBatchContext: StreamBatchContext, a stream batch handler’s context.
• PubSubContext: PubSubContext, the channel a message arrived on, under keys::Channel and keys::FromPattern.
• FredPool: keys::FredPool and PoolContext, the connection pool on every form.
• Commands: keys::Pipeline and PipelineContext, the round of a .pipeline() subscription.
• Counts: the delivery count and idle time of the claiming modes ride the DELIVERY_COUNT_HEADER and IDLE_MS_HEADER headers.

Modules

keys

Compile-time Field keys, one per native field, read with ctx.context(key).

Structs

PipelineContext

The per-delivery context of a .pipeline() subscription: the delivery’s round and the broker’s connection pool.

PoolContext

The per-delivery context that carries the broker’s connection pool and nothing else: what a handler taking Ctx<keys::FredPool> alone reads, on every form.

PubSubContext

Per-delivery context for a Redis Pub/Sub delivery (RedisPubSubMessage).

StreamBatchContext

Batch context for a batched Redis Streams subscription: what the whole subscription shares.

StreamContext

Per-delivery context for a Redis Streams delivery (RedisMessage).
