Struct EffectEnvelope 

pub struct EffectEnvelope {
    pub req_id: u64,
    pub effect: Effect,
    pub on_ok: Option<ActionEnvelope>,
    pub on_err: Option<ActionEnvelope>,
}

A queued effect with optional success/failure callbacks.

The platform executor processes the Effect, then dispatches either on_ok or on_err back into the runtime. The req_id is assigned automatically by the runtime and is globally unique within a session.

Example

// Built via the Effects builder -- you rarely construct this manually.
ctx.effects.http_get("https://example.com/api")
    .on_ok(ok_envelope)
    .on_err(err_envelope);

Fields

req_id: u64

Unique request identifier (assigned by the runtime).

effect: Effect

The effect to execute.

on_ok: Option<ActionEnvelope>

Action dispatched when the effect completes successfully.

on_err: Option<ActionEnvelope>

Action dispatched when the effect fails.

Trait Implementations

impl Clone for EffectEnvelope

fn clone(&self) -> EffectEnvelope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EffectEnvelope

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EffectEnvelope

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for EffectEnvelope

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
