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
