Cargo Features

[dependencies]
ethereum-bigint = { version = "0.2.9", default-features = false, features = ["std", "heapsizeof", "rust_arithmetic", "rlp", "string"] }
default = rlp, std, string

These default features are set whenever ethereum-bigint is added without default-features = false somewhere in the dependency tree.

std default = libc, rand

Enables std of byteorder, ethereum-hexutil, and ethereum-rlp

Affects hash::H256FastMap, hash::H256FastSet

heapsizeof = heapsize
x64asm_arithmetic rust_arithmetic
rlp default = ethereum-rlp
string default = ethereum-hexutil

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.
