Struct ChangeFact 

pub struct ChangeFact {
    pub change: [u8; 32],
    pub app: String,
    pub record: String,
    pub resource: Option<String>,
    pub at_ms: u64,
}

One change of an action, as the log indexes it: the unit it belongs to, the resource its own history entry names, and when it was made.

Fields

change: [u8; 32]

The change’s hash.

app: String

The app whose record the unit belongs to.

record: String

The record the unit belongs to.

resource: Option<String>

The resource the change’s history entry names, when it names one.

at_ms: u64

When the change was made, in milliseconds since the Unix epoch.

Implementations

impl ChangeFact

pub fn of_mutation( app: &str, record: &str, mutation: &DocumentMutation, ) -> Vec<ChangeFact>

The facts of the changes mutation carries in app’s record. Empty for a mutation that carries no change (a snapshot) and for a change that names no action: it says nothing of where it belongs.

pub fn of_payload(app: &str, record: &str, payload: &[u8]) -> Vec<ChangeFact>

The facts of the changes one signed document payload carries in app’s record: the document frame inside the commit frame it may arrive under.

pub fn of_changes( app: &str, record: &str, changes: &[Change], ) -> Vec<ChangeFact>

The facts of changes of app’s record: a document’s own history, change by change.

Trait Implementations

impl Clone for ChangeFact

fn clone(&self) -> ChangeFact

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChangeFact

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

Formats the value using the given formatter.

impl PartialEq for ChangeFact

fn eq(&self, other: &ChangeFact) -> 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.
