[features]
default = ["direct"]

## Collect statistics about cache hits etc.
statistics = []

## Enable the direct mapped apply cache implementation
direct = []

## Check that an apply cache is never dropped via its `Drop` implementation.
## This is done by adding a function call to a non-existing external function to
## the `Drop` implementation. So if the check fails, there will be a weird
## linker error. Using this feature in unoptimized builds may cause false
## positives.
static_leak_check = []

## Use the hugealloc crate to allocate memory
hugealloc = ["dep:hugealloc", "dep:allocator-api2"]

## Use parking_lot instead of spinlocks
parking_lot = []
