Struct Action 

pub struct Action {
    pub from_state: Option<ChangeId>,
    pub to_state: ChangeId,
    pub operation: Operation,
    pub description: String,
    pub semantic_changes: Vec<SemanticChange>,
    pub attribution: Attribution,
    pub timestamp: DateTime<Utc>,
    /* private fields */
}

An action records an operation between states.

Fields

from_state: Option<ChangeId>

Source state (None for initial state).

to_state: ChangeId

Destination state.

operation: Operation

Type of operation.

description: String

Human-readable description.

semantic_changes: Vec<SemanticChange>

High-level semantic changes.

attribution: Attribution

Who performed the action.

timestamp: DateTime<Utc>

When the action was performed.

Implementations

impl Action

pub fn new( from_state: Option<ChangeId>, to_state: ChangeId, operation: Operation, description: impl Into<String>, attribution: Attribution, ) -> Self

Create a new action.

pub fn with_semantic_changes(self, changes: Vec<SemanticChange>) -> Self

Add semantic changes.

pub fn add_semantic_change(&mut self, change: SemanticChange)

Add a single semantic change.

pub fn with_timestamp(self, timestamp: DateTime<Utc>) -> Self

Set the timestamp (for testing or importing).

pub fn compute_id(&self) -> ActionId

Compute the action ID from content.

pub fn id(&mut self) -> ActionId

Get the action ID, computing it if necessary.

Trait Implementations

impl Clone for Action

fn clone(&self) -> Action

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Action

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Action

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Action

fn eq(&self, other: &Action) -> 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 Serialize for Action

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
