Cargo Features

[dependencies]
merkle-tree-db = { version = "0.0.1", default-features = false, features = ["std", "executable"] }
default = std

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

std default

Enables std of hash-db ^0.15.2 and memory-db ^0.29.0

executable = hash256-std-hasher, memory-db, sha3

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.

hash256-std-hasher executable?
memory-db executable? std
