Cargo Features

solana_rbpf = { version = "0.8.1", default-features = false, features = ["jit", "fuzzer-not-safe-for-production", "debugger"] }
default = jit

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

jit default = libc, winapi
fuzzer-not-safe-for-production = arbitrary
debugger = gdbstub

Affects interpreter::DebugState, solana_rbpf::debugger, vm::EbpfVm.debug_port

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.

gdbstub debugger?

Enables gdbstub ^0.6.2

libc not win jit
winapi win jit
arbitrary fuzzer-not-safe-for-production?
