Cargo Features

[dependencies]
ethereum = { version = "0.15.0", default-features = false, features = ["std", "with-codec", "with-serde"] }
default = std

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

std default

Enables std of bytes, parity-scale-codec, ethereum-types ^0.14, hash-db, hash256-std-hasher, rlp ^0.5.2, scale-info, serde, sha3, and trie-root

serde:

Provide impls for common standard library types like Vec<T> and HashMap<K, V>.
Requires a dependency on the Rust standard library.

with-codec = codec, scale-info

Enables ethereum-types ^0.14

with-serde = serde

Enables serialize of ethereum-types ^0.14

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.

codec std with-codec?

Enables parity-scale-codec

scale-info std with-codec?
serde std with-serde?
