Enum frame_support::migrations::VersionedPostUpgradeData

pub enum VersionedPostUpgradeData {
    MigrationExecuted(Vec<u8>),
    Noop,
}

A helper enum to wrap the pre_upgrade bytes like an Option before passing them to post_upgrade. This enum is used rather than an Option to make the API clearer to the developer.

Variants

MigrationExecuted(Vec<u8>)

The migration ran, inner vec contains pre_upgrade data.

Noop

This migration is a noop, do not run post_upgrade checks.

Trait Implementations

impl Decode for VersionedPostUpgradeData

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 Encode for VersionedPostUpgradeData

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.
