Parameters:

key (int) – The key of the value
timeout (int) – The timeout seconds to wait for the value.

Returns:

The value

Return type:

bytes

Raises:

TimeoutError – When the timeout is reached.

abstract prepare() → int[source]¶

Returns:: The key of the async result.
Return type:: int

abstract set(key: int, value: bytes) → None[source]¶

Set a value to the pool.

Parameters:

key (int) – The key of the value.
value (bytes) – The value to be set.

class LocalPool(max_len: int, max_expire: int)[source]¶

Bases: AsyncResultPool

Local pool for storing results.

get(key: int, timeout: int = 5) → bytes[source]¶: Get the value with timeout

prepare() → int[source]¶
