Module pending_stdin 

The stdin of a client which waits for the container, see PendingStdin.

Structs

PendingStdin 🔒

Stdin of a client which the container did not take yet, bounded by PENDING_STDIN_MAX_BYTES. Small stdin gets merged and large stdin split into entries of at most STDIN_CHUNK_SIZE, each counts STDIN_ENTRY_OVERHEAD on top of its bytes. Empty stdin carries nothing, and nothing takes stdin after the close, both get dropped. The entries of large stdin keep its message until the container took the last one, stdin goes to the container in order, so only the oldest message is partly taken.

Constants

STDIN_CHUNK_SIZE 🔒

The largest part of stdin which goes towards the container at once. Larger stdin gets split without copying it, so that the channels on the way, which count entries, hold at most this much per entry.

STDIN_ENTRY_OVERHEAD 🔒

What an entry of the pending stdin counts on top of its bytes.

STDIN_MERGE_SIZE 🔒

Stdin smaller than this gets merged with the stdin before it while it waits, so that a client which sends a byte per message does not make the server hold far more than the bytes it counts.
