    Active {
        expiration: BlockNumber,
    },
    Inactive,
    Paused,
    Terminated,
    ExpirationChanged {

    },
    ProgramSet {
        expiration: BlockNumber,
    },
}

Type of changes applied to program in storage.

Variants

Active

Active status achieved.

Occurs when new program created or paused program was resumed.

Expiration block number presents block number when this program become paused due to losing ability to pay rent for holding.

Fields

expiration: BlockNumber

Inactive

Program become inactive forever due to gr_exit call.

Paused

Paused status.

Program is no longer available for interaction, but can be resumed by paying rent and giving whole data related to it.

Terminated

Program become inactive forever due to init failure.

ExpirationChanged

Occurs when expiration block number of a program changed.

Expiration block number presents block number when this program become paused due to losing ability to pay rent for holding.

Fields

expiration: BlockNumber

ProgramSet

Occurs when new program set in the storage.

Expiration block number presents block number when this program become paused due to losing ability to pay rent for holding or terminated in case of didn’t get initialised.

Fields

expiration: BlockNumber

Trait Implementations

impl<BlockNumber: Clone> Clone for ProgramChangeKind<BlockNumber>

fn clone(&self) -> ProgramChangeKind<BlockNumber>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<BlockNumber: Debug> Debug for ProgramChangeKind<BlockNumber>

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

Formats the value using the given formatter.

impl<BlockNumber> Decode for ProgramChangeKind<BlockNumber>

where BlockNumber: Decode,

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy, ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<BlockNumber> Encode for ProgramChangeKind<BlockNumber>

where BlockNumber: Encode,

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<BlockNumber: PartialEq> PartialEq for ProgramChangeKind<BlockNumber>

fn eq(&self, other: &ProgramChangeKind<BlockNumber>) -> 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<BlockNumber> TypeInfo for ProgramChangeKind<BlockNumber>

where BlockNumber: TypeInfo + 'static,

type Identity = ProgramChangeKind<BlockNumber>

The type identifying for which type info is provided.

fn type_info() -> Type
