Crate pg_proto 

Session-typed PostgreSQL wire protocol primitives.

Modules

auth

Authentication typestates, including the recursive SASL sub-session.

cancel

Session-external cancellation-key translation for proxies.

cleanliness

Extensible evidence for application-owned connection reuse policy.

codec

Direction-parameterised framing and lossless message decoding.

credentials

Credential transforms shared by client and proxy-side authentication policy.

demux

Filtering projection from backend messages to the typed session stream.

erased

Exact runtime erasure for storage and forwarding boundaries.

grammar

Generated PostgreSQL grammars and differential-test runtime FSMs.

integrations

Integration boundaries for platform-specific GSSAPI, Kerberos, and SSPI engines.

intermediary

Policy-neutral composition of independent downstream and upstream sessions.

pipeline

Bounded, payload-free orchestration for proxy request pipelines.

pre_startup

PostgreSQL’s untagged pre-startup protocol.

replication

Typed payloads carried inside walsender CopyData messages.

resources

Branded prepared-statement and portal resources with proxy name rewriting.

scram

Server-side SCRAM-SHA-256 and SCRAM-SHA-256-PLUS verification.

server_auth

Server-role authentication typestates for proxy-side client termination.

server_session

Server-role query sessions used when a proxy terminates the client protocol.

session

Core query, COPY, and error-draining typestates.

startup

Untagged startup messages and protocol-version negotiation.

tls

TLS transport upgrades and RFC 5929 channel binding.

transport

Buffered, cancellation-safe outbound transport.

Structs

Conn

A connection whose legal operations are selected by Phase and Cleanliness.

Enums

Dirty

The connection has state which prevents unconditional pool release.

Pristine

The connection has no known session-local changes.
