Enum OtaImageState

#[repr(u32)]
pub enum OtaImageState {
    New = 0,
    PendingVerify = 1,
    Valid = 2,
    Invalid = 3,
    Aborted = 4,
    Undefined = 4_294_967_295,
}

OTA image states for checking operability of the app.

Variants

New = 0

Monitor the first boot. The bootloader will change this to PendingVerify if auto-rollback is enabled.

You want to set this state after activating a newly installed update.

PendingVerify = 1

Bootloader changes OtaImageState::New to OtaImageState::PendingVerify to indicate the app should confirm the image as working.

Valid = 2

Set by the firmware once it’s found to be working. The bootloader will consider this Slot as working and continue to use it.

Invalid = 3

Set by the firmware once it’s found to be non-working.

The bootloader will consider this Slot as non-working and not try to boot it further.

Aborted = 4

The bootloader will change the state to OtaImageState::Aborted if the application didn’t change OtaImageState::PendingVerify to either OtaImageState::Valid or OtaImageState::Invalid.

Undefined = 4_294_967_295

Undefined. The bootloader won’t make any assumptions about the working state of this slot.

Implementations

impl OtaImageState

pub const fn from_repr(discriminant: u32) -> Option<OtaImageState>

Try to create Self from the raw representation

Trait Implementations

impl Clone for OtaImageState

fn clone(&self) -> OtaImageState

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OtaImageState

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

Formats the value using the given formatter.

impl Default for OtaImageState

fn default() -> OtaImageState

Returns the “default value” for a type.

impl Format for OtaImageState

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.

impl Hash for OtaImageState

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given [Hasher].

impl PartialEq for OtaImageState

fn eq(&self, other: &OtaImageState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<u32> for OtaImageState

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: u32) -> Result<Self, Self::Error>

Performs the conversion.
