brain-edge configuration.

Fields

listen_addr: SocketAddr

Address to serve the HTTP API on.

brain_addr: SocketAddr

Address of the Brain database to proxy to.

pool_size: usize

Per-credential connection-pool width to Brain.

max_credentials: usize

Hard cap on distinct cached credentials (LRU-evicted over this).

idle_ttl_secs: u64

Seconds of idle before a cached credential’s pool is swept.

request_timeout_secs: u64

Per-request wall-clock timeout, in seconds. A request that outlives this (e.g. a stalled Brain connection) is cut with 408 Request Timeout rather than hanging a worker indefinitely.

max_body_bytes: usize

Hard cap on request body size, in bytes. Bodies over this are rejected with 413 Payload Too Large before the handler runs.

wire_listen_addr: Option<SocketAddr>

Optional address for the transparent wire-protocol proxy listener. When Some, the edge serves the Brain binary wire protocol here (in addition to the HTTP data plane) — a customer SDK points at this address with its own Brain key and the edge splices frames to Brain untouched. None (the default) leaves the proxy off; the edge is HTTP-only.

wire_rate_capacity: u32

Wire-proxy per-credential rate-limit burst ceiling. 0 (the default) disables rate limiting on the wire path.

wire_rate_refill_per_sec: u32

Wire-proxy per-credential sustained rate, in ops per second, refilled into the burst bucket. Ignored when wire_rate_capacity is 0.

Implementations

impl EdgeConfig

pub fn from_env() -> Result<Self, String>

Load from the environment with sane self-host defaults.

• BRAIN_EDGE_LISTEN — HTTP listen addr (default 0.0.0.0:8080).
• BRAIN_ADDR — Brain address, ip:port or host:port (default 127.0.0.1:7878).
• BRAIN_EDGE_POOL_SIZE — pool width per credential (default 4).
• BRAIN_EDGE_MAX_CREDENTIALS — cap on cached credentials (default 256).
• BRAIN_EDGE_IDLE_TTL_SECS — idle-sweep TTL in seconds (default 900).
• BRAIN_EDGE_REQUEST_TIMEOUT_SECS — per-request timeout (default 30).
• BRAIN_EDGE_MAX_BODY_BYTES — request body cap (default 1048576 = 1 MiB).
• BRAIN_EDGE_WIRE_LISTEN — wire-proxy listen addr, ip:port or host:port (unset = wire proxy off).
• BRAIN_EDGE_WIRE_RATE_CAPACITY — per-credential burst (default 0 = off).
• BRAIN_EDGE_WIRE_RATE_REFILL_PER_SEC— per-credential ops/sec refill (default 0).

Errors

Returns a message if an address fails to parse/resolve, a numeric var is malformed, or a required-positive value is zero.
