Struct exonum_supervisor::MigrationRequest

#[non_exhaustive]pub struct MigrationRequest {
    pub new_artifact: ArtifactId,
    pub service: String,
    pub deadline_height: Height,
    pub seed: u64,
}

Request for the service data migration.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

new_artifact: ArtifactId

New artifact identifier.

service: String

Name of service for a migration.

deadline_height: Height

The height until which the migration procedure should be completed.

seed: u64

Seed to allow several migrations with the same params.

Methods

impl MigrationRequest

pub fn new(
    new_artifact: ArtifactId,
    service: impl Into<String>,
    deadline_height: Height
) -> Self

Creates a new migration request.

Trait Implementations

impl BinaryKey for MigrationRequest

fn size(&self) -> usize

Returns the size of the serialized key in bytes.

fn write(&self, buffer: &mut [u8]) -> usize

Serializes the key into the specified buffer of bytes.

fn read(buffer: &[u8]) -> Self::Owned

Deserializes the key from the specified buffer of bytes.

impl BinaryValue for MigrationRequest

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

Serializes the given value to the vector of bytes.

fn from_bytes(value: Cow<[u8]>) -> Result<Self, Error>

Deserializes the value from the given bytes array.

fn into_bytes(self) -> Vec<u8>

Consumes and serializes the given value to the vector of bytes. This method is faster with the wrapped values, thus if you wouldn't use value after serialization use it.

impl Clone for MigrationRequest

fn clone(&self) -> MigrationRequest

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MigrationRequest

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MigrationRequest

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl From<MigrationRequest> for MigrationInfoQuery

fn from(request: MigrationRequest) -> Self

Performs the conversion.

impl ObjectHash for MigrationRequest

fn object_hash(&self) -> Hash

Returns a hash of the value.

impl PartialEq<MigrationRequest> for MigrationRequest

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl ProtobufConvert for MigrationRequest

type ProtoStruct = MigrationRequest

Type generated from the Protobuf definition.

fn from_pb(pb: Self::ProtoStruct) -> Result<Self, Error>

Performs conversion from the type generated from Protobuf.

fn to_pb(&self) -> Self::ProtoStruct

Performs conversion to the type generated from Protobuf.

impl Serialize for MigrationRequest

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for MigrationRequest

impl TryFrom<MigrationInfoQuery> for MigrationRequest

type Error = Error

The type returned in the event of a conversion error.

fn try_from(query: MigrationInfoQuery) -> Result<Self, Self::Error>

Performs the conversion.
