Trait Implementations

impl<T: Config> Decode for Migration<T>where Option<<T as Config>::Hash>: 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<T: Config> Default for Migration<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: Config> Encode for Migration<T>where Option<<T as Config>::Hash>: Encode,

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

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

fn size_hint(&self) -> usize

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

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<T: Config> MaxEncodedLen for Migration<T>where Option<<T as Config>::Hash>: MaxEncodedLen,

fn max_encoded_len() -> usize

Upper bound, in bytes, of the maximum encoded size of this item.

impl<T: Config> MigrationStep for Migration<T>

const VERSION: u16 = 9u16

Returns the version of the migration.

fn max_step_weight() -> Weight

Returns the maximum weight that can be consumed in a single step.

fn step(&mut self) -> (IsFinished, Weight)

Process one step of the migration.

fn pre_upgrade_step() -> Result<Vec<u8>, TryRuntimeError>

Execute some pre-checks prior to running the first step of this migration.

fn post_upgrade_step(state: Vec<u8>) -> Result<(), TryRuntimeError>

Execute some post-checks after running the last step of this migration.

fn integrity_test(max_block_weight: Weight)

Verify that the migration step fits into Cursor, and that max_step_weight is not greater than max_block_weight.
