Struct EventId 

pub struct EventId(/* private fields */);

Primary key of an outbox row.

Wraps a Uuid so that event identifiers are not confused with other UUID-valued columns. Default produces a fresh random v4 identifier.

Implementations

impl EventId

pub fn load(id: Uuid) -> Self

Wraps an existing Uuid — typically used by storage adapters when hydrating an Event from a database row.

pub fn as_uuid(&self) -> Uuid

Returns the underlying Uuid for use with APIs that need one (e.g. logging or foreign-key references).

Trait Implementations

impl Clone for EventId

fn clone(&self) -> EventId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for EventId

impl Debug for EventId

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

Formats the value using the given formatter.

impl<'r, DB: Database> Decode<'r, DB> for EventId

where Uuid: Decode<'r, DB>,

fn decode( value: <DB as Database>::ValueRef<'r>, ) -> Result<Self, Box<dyn Error + Send + Sync + 'static>>

Decode a new value of this type using a raw value from the database.

impl Default for EventId

fn default() -> Self

Generates a fresh random identifier (UUID v4).

impl<'q, DB: Database> Encode<'q, DB> for EventId

where Uuid: Encode<'q, DB>,

fn encode_by_ref( &self, buf: &mut <DB as Database>::ArgumentBuffer<'q>, ) -> Result<IsNull, BoxDynError>

Writes the value of self into buf without moving self.

fn produces(&self) -> Option<DB::TypeInfo>

fn size_hint(&self) -> usize

fn encode( self, buf: &mut <DB as Database>::ArgumentBuffer<'q>, ) -> Result<IsNull, Box<dyn Error + Send + Sync>>

where Self: Sized,

Writes the value of self into buf in the expected format for the database.

impl Eq for EventId

impl Hash for EventId

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

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 PartialEq for EventId

fn eq(&self, other: &EventId) -> 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 PgHasArrayType for EventId

where Uuid: PgHasArrayType,

fn array_type_info() -> PgTypeInfo

fn array_compatible(ty: &PgTypeInfo) -> bool

impl StructuralPartialEq for EventId

impl<DB: Database> Type<DB> for EventId

where Uuid: Type<DB>,

fn type_info() -> DB::TypeInfo

Returns the canonical SQL type for this Rust type.

fn compatible(ty: &DB::TypeInfo) -> bool

Determines if this Rust type is compatible with the given SQL type.
