Enum kernel::ErrorCode[][src]

#[repr(usize)]pub enum ErrorCode {
    FAIL,
    BUSY,
    ALREADY,
    OFF,
    RESERVE,
    INVAL,
    SIZE,
    CANCEL,
    NOMEM,
    NOSUPPORT,
    NODEVICE,
    UNINSTALLED,
    NOACK,
}

Standard errors in Tock.

In contrast to [Result<(), ErrorCode>](crate::Result<(), ErrorCode>) this does not feature any success cases and is therefore more appropriate for the Tock 2.0 system call interface, where success payloads and errors are not packed into the same 32-bit wide register.

Variants

FAIL

Generic failure condition

BUSY

Underlying system is busy; retry

ALREADY

The state requested is already set

OFF

The component is powered down

RESERVE

Reservation required before use

INVAL

An invalid parameter was passed

SIZE

Parameter passed was too large

CANCEL

Operation canceled by a call

NOMEM

Memory required not available

NOSUPPORT

Operation is not supported

NODEVICE

Device is not available

UNINSTALLED

Device is not physically installed

NOACK

Packet transmission not acknowledged
