# These two features are used for `no_std` builds for the environments which already provides

# This feature flag controls the runtime's behavior when encountering
# a panic or when it runs out of memory, improving the diagnostics.
#
# When enabled the runtime will marshal the relevant error message
# to the host through the `PanicHandler::abort_on_panic` runtime interface.
# This gives the caller direct programmatic access to the error message.
#
# When disabled the error message will only be printed out in the
# logs, with the caller receiving a generic "wasm `unreachable` instruction executed"
# error message.
#
# This has no effect if both `disable_panic_handler` and `disable_oom`
# are enabled.
#
# WARNING: Enabling this feature flag requires the `PanicHandler::abort_on_panic`
#          host function to be supported by the host. Do *not* enable it for your
#          runtime without first upgrading your host client!
