Expand description

Standard errors in Tock.

Each error code is assigned a fixed usize nonzero number. In effect, 0 is reserved for “no error” / “success”.

Variants§

§

FAIL = 1

Generic failure condition

§

BUSY = 2

Underlying system is busy; retry

§

ALREADY = 3

The state requested is already set

§

OFF = 4

The component is powered down

§

RESERVE = 5

Reservation required before use

§

INVAL = 6

An invalid parameter was passed

§

SIZE = 7

Parameter passed was too large

§

CANCEL = 8

Operation canceled by a call

§

NOMEM = 9

Memory required not available

§

NOSUPPORT = 10

Operation is not supported

§

NODEVICE = 11

Device is not available

§

UNINSTALLED = 12

Device is not physically installed

§

NOACK = 13

Packet transmission not acknowledged
