Cargo Features

[dependencies]
risc0-zkvm = { version = "0.21.0", default-features = false, features = ["client", "cuda", "dual", "metal", "disable-dev-mode", "docker", "getrandom", "std", "prove"] }

default = client

The client feature is set by default whenever risc0-zkvm is added without default-features = false somewhere in the dependency tree.

client default prove? = std

Enables bincode, bonsai-sdk, bytes, prost, prost-build, protobuf-src, and tempfile

cuda = prove

Enables cuda of risc0-circuit-recursion, risc0-circuit-rv32im, and risc0-zkp

dual

metal = prove

Enables metal of risc0-circuit-recursion, risc0-circuit-rv32im, and risc0-zkp

disable-dev-mode

docker

This flag uses the docker environment to build test guests such as multi-test to ensure accurate cycle and segment counts. Tests that have been gated on this flag measure cycles and segments. Without this flag, the rust build system will generate binaries that not identical across all architectures.
While this is acceptable for most tests, the tests counting cycles and segments will fail intermittently.

Enables docker of risc0-groth16

getrandom

The zkVM exposes a getrandom implementation that panics by default. This will expose a getrandom implementation that uses the sys_random ecall.

Enables getrandom of risc0-zkvm-platform

std client prove?

Enables std of anyhow, hex, optional num-traits, risc0-binfmt, risc0-groth16, risc0-zkp, serde, and sha2

serde:

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

prove cuda? metal? = client, std

Enables rustc-demangle, tempfile, and typetag, addr2line ^0.21, bincode, bytes, crypto-bigint, elf, human-repr, lazy-regex, num-traits, prost, rayon, prost-build, and protobuf-src, prove of risc0-circuit-recursion, risc0-circuit-rv32im, risc0-groth16, and risc0-zkp
