[features]
## Enable agent card signing (JWS, RFC 8785 canonicalization).
signing = ["a2a-protocol-types/signing"]
## Enable structured logging via the `tracing` crate (zero cost when disabled).
tracing = ["dep:tracing"]
## Enable SQLite-backed task and push config stores via `sqlx`.
sqlite = ["dep:sqlx"]
## Enable PostgreSQL-backed task and push config stores via `sqlx` with PostgreSQL driver.
postgres = ["dep:sqlx", "sqlx/postgres", "sqlx/json"]
## Enable WebSocket transport via `tokio-tungstenite`.
websocket = ["dep:tokio-tungstenite", "dep:futures-util"]
## Enable gRPC transport via `tonic`.
grpc = ["dep:tonic", "dep:prost", "dep:tokio-stream", "dep:tonic-build"]
## Enable OpenTelemetry integration for native OTLP export of traces and metrics.
otel = ["dep:opentelemetry", "dep:opentelemetry_sdk", "dep:opentelemetry-otlp"]
## Enable Axum framework integration (Router, extractors, IntoResponse).
axum = ["dep:axum"]
