Cargo Features

sp-session = { version = "34.0.0", default-features = false, features = ["std"] }
default = std

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

std default

Enables std of parity-scale-codec, scale-info, sp-api, sp-core, sp-keystore, sp-runtime, and sp-staking

Affects sp-session::generate_initial_session_keys

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.
