pub struct CommandContext {
    pub actor: ActorRef,
    pub idempotency_key: Option<String>,
    pub metadata: BTreeMap<String, String>,
}

Metadata attached to a command for audit and observation.

Fields

actor: ActorRef

Actor responsible for the command.

idempotency_key: Option<String>

Optional idempotency key supplied by the application.

metadata: BTreeMap<String, String>

Opaque application context.

Implementations

impl CommandContext

pub const fn new(actor: ActorRef) -> Self

Creates a command context for an actor.

pub fn with_idempotency_key(self, key: impl Into<String>) -> Self

Adds an idempotency key.

pub fn with_metadata( self, key: impl Into<String>, value: impl Into<String>, ) -> Self

Adds an opaque application metadata attribute.

pub fn validate(&self) -> Result<()>

Validates the command context.

Trait Implementations

impl Clone for CommandContext

fn clone(&self) -> CommandContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CommandContext

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CommandContext

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for CommandContext

impl PartialEq for CommandContext

fn eq(&self, other: &CommandContext) -> 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 CommandContext

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
