# Enable tokio_unstable cfg for dial9-tokio-telemetry support
# This allows dial9 to hook into Tokio's internal runtime events
[build]
# Enable Tokio unstable features required by dial9-tokio-telemetry for runtime tracing.
# See: https://docs.rs/tokio/latest/tokio/#unstable-features

# Enable frame pointers for CPU profiling (Linux only, optional but recommended)
# Uncomment the following line for better CPU profiling data

# dial9 Tokio Runtime Telemetry Configuration
# ============================================================================
# dial9 provides low-overhead Tokio runtime-level telemetry for performance diagnostics.
# It captures events like PollStart/End, WorkerPark/Unpark, QueueSample, TaskSpawn.
#
# Features:
# - CPU overhead < 5% (with sampling rate 1.0)
# - Automatic file rotation (configurable size and count)
# - Graceful degradation if initialization fails
#
# Note: Disabled by default. Enable only when needed for runtime diagnostics.
# Note: Requires build flag --cfg tokio_unstable (set in .cargo/config.toml).
