[features]
default = []
# Tokio runtime-level telemetry. Requires a `--cfg tokio_unstable` build; the
# build script fails the compile when that flag is missing. Off by default so
# ordinary builds neither pay for nor depend on Tokio's unstable API.
dial9 = ["dep:dial9-tokio-telemetry"]
#
# NOTE: there is deliberately no `dial9-taskdump` feature. dial9 only captures a
# task dump for futures it wrapped itself, i.e. those spawned via
# `dial9_tokio_telemetry::spawn`. RustFS spawns with `tokio::spawn` throughout,
# so enabling `tokio/taskdump` would cost a Linux-only build constraint and
# record nothing. Measured on an identical workload: 0 dumps via `tokio::spawn`,
# 14709 via `dial9::spawn`. Re-adding this feature only makes sense together
# with migrating the paths under investigation to dial9's spawner.
# See rustfs/backlog#1157 (D9-16) and dial9-rs/dial9#477.
#
# NOTE: there is deliberately no `dial9-s3` feature. dial9's `worker-s3` feature
# pulls aws-sdk-s3-transfer-manager 0.1.3 (its latest), which pins
# aws-smithy-http-client onto hyper-rustls 0.24 / rustls-webpki 0.101.7. That
# webpki carries RUSTSEC-2026-0098, -0099 and -0104, and `cargo deny` rejects it.
# Feature unification cannot drop a transitive dependency, so this can only be
# fixed upstream. Tracked in rustfs/backlog#1157 (D9-14).
