Module conn_string 

Connection-string parser shared across reddb, reddb-client, red_client, and every language driver.

Pure function over a string; no I/O, no allocation beyond what the returned ConnectionTarget needs. The grammar is defined by docs/clients/connection-strings.md; this module is the canonical parser and is the single source of truth consumed by the rest of the workspace.

The parser ports the logic that previously lived in drivers/rust/src/connect.rs (which keeps a thin re-export layer for backwards compatibility while drivers migrate over). Cluster URIs (grpc://primary,replica:port), default ports per scheme, and the ?route=primary override behave identically to the original.

Structs

ConnStringLimits

DoS guardrails applied by parse before any URI work happens.

ParseError

Error returned by parse.

Enums

ConnectionTarget

Normalised target produced by parse.

ParseErrorKind

Stable error code for parser failures.

Constants

DEFAULT_PORT_GRPC

DEFAULT_PORT_RED

Default port per documented scheme. Centralised so other crates (the connector, server-side dispatch) can stay consistent.

Functions

parse

Parse a connection URI into a ConnectionTarget under the default DoS limits.

parse_with_limits

Same as parse but with caller-supplied DoS guardrails. Useful for tests that need tighter limits or for callers (a future admin tool, an offline validator) that need to relax the defaults.
