Enum CodeChangeKind 

pub enum CodeChangeKind<BlockNumber> {
    Active {
        expiration: Option<BlockNumber>,
    },
    Inactive,
    Reinstrumented,
}

Type of changes applied to code in storage.

Variants

Active

Code become active and ready for use.

Appear when new code created or expiration block number updated.

Expiration block number presents block number when this code become inactive due to losing ability to pay rent for holding. Equals None if stores free (some program relays on it, see #646).

Fields

expiration: Option<BlockNumber>

Inactive

Code become inactive and can no longer be used.

Reinstrumented

Code was reinstrumented.

Trait Implementations

impl<BlockNumber: Clone> Clone for CodeChangeKind<BlockNumber>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<BlockNumber: Debug> Debug for CodeChangeKind<BlockNumber>

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

Formats the value using the given formatter.

impl<BlockNumber> Decode for CodeChangeKind<BlockNumber>

where Option<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 CodeChangeKind<BlockNumber>

where Option<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 CodeChangeKind<BlockNumber>

fn eq(&self, other: &CodeChangeKind<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 CodeChangeKind<BlockNumber>

where Option<BlockNumber>: TypeInfo + 'static, BlockNumber: TypeInfo + 'static,

type Identity = CodeChangeKind<BlockNumber>

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl<BlockNumber> EncodeLike for CodeChangeKind<BlockNumber>

where Option<BlockNumber>: Encode,

impl<BlockNumber: Eq> Eq for CodeChangeKind<BlockNumber>

impl<BlockNumber> StructuralPartialEq for CodeChangeKind<BlockNumber>
