Struct frame_system::LastRuntimeUpgradeInfo

pub struct LastRuntimeUpgradeInfo {
    pub spec_version: Compact<u32>,
    pub spec_name: Cow<'static, str>,
}

Stores the spec_version and spec_name of when the last runtime upgrade happened.

Fields

spec_version: Compact<u32>

spec_name: Cow<'static, str>

Implementations

impl LastRuntimeUpgradeInfo

pub fn was_upgraded(&self, current: &RuntimeVersion) -> bool

Returns if the runtime was upgraded in comparison of self and current.

Checks if either the spec_version increased or the spec_name changed.

Trait Implementations

impl Debug for LastRuntimeUpgradeInfo

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

Formats the value using the given formatter.

impl Decode for LastRuntimeUpgradeInfo

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 LastRuntimeUpgradeInfo

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 From<RuntimeVersion> for LastRuntimeUpgradeInfo

fn from(version: RuntimeVersion) -> Self

Converts to this type from the input type.

impl PartialEq for LastRuntimeUpgradeInfo

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TypeInfo for LastRuntimeUpgradeInfo

type Identity = LastRuntimeUpgradeInfo

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
