Cargo Features

[dependencies]
pallet-timestamp = { version = "37.0.0", default-features = false, features = ["std", "try-runtime", "runtime-benchmarks"] }
default = std

The std feature is set by default whenever pallet-timestamp is added without default-features = false somewhere in the dependency tree.

std default

Enables std of parity-scale-codec, optional frame-benchmarking, frame-support, frame-system, log, scale-info, sp-inherents, optional sp-io, sp-runtime, sp-storage, and sp-timestamp

try-runtime

Enables try-runtime of frame-support, frame-system, and sp-runtime

runtime-benchmarks = sp-io

Enables runtime-benchmarks of frame-benchmarking, frame-support, frame-system, and sp-runtime

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.

frame-benchmarking runtime-benchmarks?
sp-io runtime-benchmarks?
