Feature flags of risc0-zkvm crate // Lib.rs

Cargo Features

[dependencies]
risc0-zkvm = { version = "5.0.0-rc.1", default-features = false, features = ["circuit_debug", "client", "bonsai", "cuda", "dual", "disable-dev-mode", "docker", "getrandom", "heap-embedded-alloc", "std", "metal", "prove", "redis", "unstable", "witgen_debug", "block_tracker_debug"] }

default = bonsai, client

These default features are set whenever risc0-zkvm is added without default-features = false somewhere in the dependency tree.

circuit_debug

Enables circuit_debug of risc0-zkp

client default prove? = std

Enables bincode ^1.3, bytes, lazy-regex, prost ^0.13, risc0-build, rzup, and tempfile

Affects risc0-zkvm::rpc…

bonsai default

Enables bonsai-sdk

cuda dual? = prove

Enables cuda of risc0-circuit-keccak, risc0-circuit-recursion, risc0-circuit-rv32im, risc0-groth16, and risc0-zkp

risc0-circuit-keccak:
Enables CUDA GPU support

dual = cuda

Enables dual of risc0-circuit-recursion

r0vm-ver-compat 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. It does not effect non-test code.

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

heap-embedded-alloc

The zkVM uses a bump-pointer heap allocator by default which does not free memory. This will use a slower linked-list heap allocator to reclaim memory.

Enables heap-embedded-alloc of risc0-zkvm-platform
