Timeout layer

Add timeout for every operation to avoid slow or unexpected hang operations.

Notes

TimeoutLayer treats all operations in two kinds:

• Non IO Operation like stat, delete they operate on a single file. We control them by setting timeout.
• IO Operation like read, Reader::read and Writer::write, they operate on data directly, we control them by setting io_timeout.

Default

• timeout: 60 seconds
• io_timeout: 10 seconds

Examples

const op = new Operator("fs", { root: "/tmp" })

const timeout = new TimeoutLayer();
timeout.timeout = 10000;      // 10 seconds for non-IO ops (in milliseconds)
timeout.ioTimeout = 3000;     // 3 seconds for IO ops (in milliseconds)

op.layer(timeout.build());
