}Expand description
A wrapper structure for the coverage and backtrace address spaces. The current mode is
defined by the value stored in mode which is either VirtMemMode::Coverage or
VirtMemMode::Backtrace.
Fields
mode: VirtMemModeThe address space type currently in use by the fuzzer.
covtrace: RefCell<VirtMemAllocator>The address space where coverage hooks are applied.
covtrace_snapshot: RefCell<VirtMemAllocator>Snapshot of the address space where coverage hooks are applied.
backtrace: RefCell<VirtMemAllocator>The address space where backtrace hooks are applied.
backtrace_snapshot: RefCell<VirtMemAllocator>Snapshot of the address space where backtrace hooks are applied.
