Do not modify the discriminants in this structure. They are used in libstd directly.

Variants

ElapsedMs = 0

Get the elapsed time in milliseconds

SleepMs = 1

Sleep for the specified numer of milliseconds

RecalculateSleep = 2

Recalculate the sleep time

SuspendResume = 3

Suspend/resume callback

PingWdt = 4

force a WDT update

GetVersion = 5

Return the version string of Xous. We bury it here because this is a small, lightweight server we can rebuild on every run.

LockMutex = 6

Lock the given Mutex, blocking if it is already locked.

Arguments

arg1: An integer of some sort, such as the address of the Mutex

UnlockMutex = 7

Unlock the given Mutex

Arguments

arg1: An integer of some sort, such as the address of the Mutex

WaitForCondition = 8

Wait for a given condition to be signalled

Arguments

arg1: An integer of some sort, such as the address of the Condvar arg2: The number of milliseconds to wait, or 0 to wait forever

NotifyCondition = 9

Notify a condition

Arguments

arg1: An integer of some sort, such as the address of the Condvar arg2: The number of conditions to notify

FreeMutex = 10

Free a Mutex

This call will free a Mutex that was previously Locked or Unlocked. Doing so causes the Mutex to be unlocked.

Arguments

arg1: The integer that matches the Mutex value

FreeCondition = 11

Free a Condition

This call will free a Condition that was previously waited upon. All pending threads will be forgotten.

Arguments

arg1: The integer that matches the Condition value

InvalidCall = 4_294_967_295

Invalid call – an error occurred decoding the opcode

Trait Implementations

impl Debug for Opcode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromPrimitive for Opcode

fn from_i64(n: i64) -> Option<Self>

fn from_u64(n: u64) -> Option<Self>

Converts an u64 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_isize(n: isize) -> Option<Self>

Converts an isize to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_i8(n: i8) -> Option<Self>

Converts an i8 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.
