Types

type CapabilityRestrictionConfig

type CapabilityRestrictionConfig struct {

	// The Proxy-Wasm capabilities which will be allowed. Capabilities are mapped by
	// name. The “SanitizationConfig“ which each capability maps to is currently unimplemented and ignored,
	// and so should be left empty.
	//
	// The capability names are given in the
	// `Proxy-Wasm ABI <https://github.com/proxy-wasm/spec/tree/master/abi-versions/vNEXT>`_.
	// Additionally, the following WASI capabilities from
	// `this list <https://github.com/WebAssembly/WASI/blob/master/phases/snapshot/docs.md#modules>`_
	// are implemented and can be allowed:
	// “fd_write“, “fd_read“, “fd_seek“, “fd_close“, “fd_fdstat_get“, “environ_get“, “environ_sizes_get“,
	// “args_get“, “args_sizes_get“, “proc_exit“, “clock_time_get“, “random_get“.
