# at 0.23.41 / 0.26.4 — verified). The tls-rustls feature enables

# redis 0.27: Valkey/Redis client for ValkeyEventSink (deploy spec §5.6).
# BSD-3-Clause (verified via docs.rs/redis + crates.io API), cargo-deny clean against
# the deny.toml allow list (line 88). Pinned to 0.27 (NOT 1.3.0) because redis 1.3.0
# requires Rust 1.88, conflicting with the workspace MSRV of 1.85
# (rust-toolchain.toml). redis 0.27.6 has MSRV 1.70, well within 1.85.
# Features:
#  - aio: async API (ConnectionManager, AsyncCommands)
#  - streams: XADD MAXLEN ~ (the capped-stream primitive, StreamMaxlen::Approx)
#  - tokio-comp: tokio runtime adapter
# Used only by crates/rutster/src/valkey_sink.rs. default-features = false deliberately DROPS
# the redis crate's TLS feature — TLS to Valkey is the operator's network posture
# (ADR-0005 sub-ms rule), not a rutster code path.
redis = { version = "0.27", default-features = false, features = ["aio", "streams", "tokio-comp"] }
# rcgen NOTE: rcgen 0.14.8 bumped MSRV to Rust 1.88, breaking the 1.85
# toolchain matrix. rcgen is a transitive dep via dimpl → str0m 0.21 →
# rutster-media. Cargo.lock pins it to 0.14.7 (the minimum satisfying
# dimpl's ^0.14.7 constraint) to keep the 1.85 MSRV safety net. If a
# `cargo update` bumps it past 0.14.7, the 1.85 CI job will fail — re-pin
# with `cargo update -p rcgen --precise 0.14.7`. When the project bumps
# rust-toolchain.toml past 1.88, this pin can be dropped.
