Module state 

A representation of Sōzu’s state

Structs

CertificateMetadata

Runtime selection metadata attached to one stored TLS certificate.

CertificateMetadataIndex

Metadata for every certificate on one listener address.

ConfigState

The ConfigState represents the state of Sōzu’s business, which is to forward traffic from frontends to backends. Hence, it contains all details about:

Enums

StateError

Functions

merge_custom_http_answers

Merge a CustomHttpAnswers patch into the listener’s stored answers, preserving any field not present in the patch.

rollback_request

Build the unambiguous inverse of a mutating request.

validate_alpn_protocols

Validate an AlpnProtocols patch: each value must be “h2” or “http/1.1”. Empty values vec is allowed (reset-to-default).

validate_forwarded_headers

Validate a forwarded_headers wire value: it must name a ForwardedHeaders variant. prost decodes an unknown enum number into the raw i32, and the listener getter would silently read it as the default; a patch carrying one is refused instead.

validate_h2_flood_knobs_http

Validate all H2 flood knobs in an HTTP listener patch.

validate_h2_flood_knobs_http_listener

Validate the H2 knobs of a complete HTTP listener configuration, on the AddHttpListener path (sozu-proxy/sozu#1418).

validate_h2_flood_knobs_https

Validate all H2 flood knobs in an HTTPS listener patch (same rules as HTTP).

validate_h2_flood_knobs_https_listener

Validate the H2 knobs of a complete HTTPS listener configuration, on the AddHttpsListener path (same rules as validate_h2_flood_knobs_http_listener).

validate_hsts_patch

Validate the hsts block of an UpdateHttpsListenerConfig patch: it replaces the listener default whole, and enabled is what tells “disable” from “enable”, so a block without it is refused — on the main process here, on the worker with ListenerError::HstsEnabledRequired.

validate_sozu_id_header

Validate a sozu_id_header value against the RFC 9110 §5.1 token grammar:

Type Aliases

ClusterId

To use throughout Sōzu
