Module startup 

Startup preflight, phase-aware diagnostics, and typed error mapping.

The server startup sequence is divided into explicit phases. Each phase produces a typed error that preserves the underlying cause chain and identifies the failing phase so operators can act on the first failure without guessing which stage broke.

Structs

StartupError

Top-level startup error carrying phase context and a typed cause.

Enums

StartupErrorKind

Typed cause attached to a StartupError.

StartupPhase

Discrete phases of the server startup sequence.

TlsFileStatus

Classification of a single TLS file check.

Functions

bind_tcp_listener

Bind a TCP listener and classify failures under the bind phase.

build_tls_server_config

Build a rustls::ServerConfig from the resolved Config.

check_tls_file

Check whether a single path refers to a readable regular file.

log_phase

log_startup_failure

Log a startup failure at ERROR level with phase context.

log_transport_summary

Log transport diagnostics after config validation succeeds.

preflight_tls_files

Run preflight checks on all configured TLS file paths.
