Struct Change 

pub struct Change {
    pub timestamp_nanos: u64,
    pub canister_version: u64,
    pub origin: ChangeOrigin,
    pub details: Option<ChangeDetails>,
}

Change

Represents a canister change as stored in the canister history.

Fields

timestamp_nanos: u64

The system timestamp (in nanoseconds since Unix Epoch) at which the change was performed.

canister_version: u64

The canister version after performing the change.

origin: ChangeOrigin

The change’s origin (a user or a canister).

details: Option<ChangeDetails>

The change’s details.

Trait Implementations

impl CandidType for Change

fn _ty() -> Type

fn id() -> TypeId

fn idl_serialize<__S>( &self, __serializer: __S, ) -> Result<(), <__S as Serializer>::Error>

where __S: Serializer,

fn ty() -> Type

impl Clone for Change

fn clone(&self) -> Change

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Change

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Change

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Change

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Change

fn cmp(&self, other: &Change) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Change

fn eq(&self, other: &Change) -> 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 PartialOrd for Change

fn partial_cmp(&self, other: &Change) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Change

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
