Module sockets 

Socket quota tracking and WASI socket host implementations.

This module provides SocketPermitState, SpinSocketsView, and SpinSockets — the types needed to intercept WASI TCP/UDP socket creation and enforce a per-app cap on the number of concurrently open sockets.

Structs

SocketPermitState

Shared state for tracking per-socket semaphore permits. Permits are acquired when a socket is allocated and released when the socket resource is dropped.

SpinSockets

HasData accessor for SpinSocketsView, used in place of WasiSockets when registering TCP socket bindings so that socket creation and drop can participate in socket quota tracking.

SpinSocketsView

A view over WASI socket state that carries an optional per-instance socket permit store, enabling per-connection quota tracking.
