Enum pavex::blueprint::constructor::Lifecycle

pub enum Lifecycle {
    Singleton,
    RequestScoped,
    Transient,
}

How many times should a constructor be invoked?

Variants

Singleton

The constructor for a Singleton type is invoked at most once.

As a consequence, there is at most one instance of Singleton types, stored inside the server’s global state.

RequestScoped

The constructor for a RequestScoped type is invoked at most once for every incoming request.

As a consequence, there is at most one instance of RequestScoped types for every incoming request.

Transient

The constructor for a Transient type is invoked every single time an instance of the type is required.

As a consequence, there can be multiple instances of Transient types for every incoming request.

Trait Implementations

impl Clone for Lifecycle

fn clone(&self) -> Lifecycle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Lifecycle

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Lifecycle

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Lifecycle

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

Formats the value using the given formatter.

impl Hash for Lifecycle

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 Lifecycle

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Lifecycle

impl Eq for Lifecycle

impl StructuralPartialEq for Lifecycle
