Cargo Features

bitcoin_hashes = { version = "0.14.0", default-features = false, features = ["std", "alloc", "io", "small-hash", "schemars", "serde"] }
default = std

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

std default = alloc

Enables std of bitcoin-io and hex-conservative

alloc std

Enables alloc of hex-conservative

io = bitcoin-io

If you want I/O you must enable either "std" or "io".


Smaller (but slower) implementation of sha256, sha512 and ripemd160

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.

schemars implicit feature

Enables schemars


Generate JSON Schemas from Rust code

serde implicit feature
