- default = std
-
The
std
feature is set by default wheneverframe-support
is added without
somewhere in the dependency tree.default-features = false - std default
-
Enables std of parity-scale-codec, environmental, frame-metadata ^16.0.0, frame-support-procedural, k256, log, scale-info, serde, serde_json, sp-api, sp-arithmetic, sp-core, sp-debug-derive, sp-genesis-builder, sp-inherents, sp-io, sp-metadata-ir, sp-runtime, sp-staking, sp-state-machine, sp-std, sp-tracing, and sp-weights
serde:
Provide impls for common standard library types like Vec<T> and HashMap<K, V>.
Requires a dependency on the Rust standard library.Affects
frame-support::testing_prelude
,migrations::SteppedMigrations.integrity_test
,hooks::GenesisBuild.build_storage
,hooks::GenesisBuild.assimilate_storage
… - try-runtime
-
Enables try-runtime of sp-runtime and force-debug of sp-debug-derive
sp-debug-derive:
By default
RuntimeDebug
implementsDebug
that outputs<wasm:stripped>
whenstd
is disabled. However, sometimes downstream users need to have the realDebug
implementation for debugging purposes. If this is required, a user only needs to add this crate as a dependency of their runtime and enable theforce-debug
feature.Affects

… - no-metadata-docs
-
By default some types have documentation,
no-metadata-docs
allows to reduce the documentation in the metadata.Enables no-metadata-docs of frame-support-procedural and sp-api
- full-metadata-docs
-
By default some types have documentation,
full-metadata-docs
allows to add documentation to more types in the metadata.Enables docs of scale-info
- tuples-96
-
Generate impl-trait for tuples with the given number of tuples. Will be needed as the number of pallets in a runtime grows. Does increase the compile time!
Enables tuples-96 of frame-support-procedural
- tuples-128
-
Enables tuples-128 of frame-support-procedural
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.
