Struct Effects 

pub struct Effects { /* private fields */ }

Captured effects from an operation. This struct can be used to return Effects from a turbo-tasks function and apply them later.

Implementations

impl Effects

pub fn cell(self) -> Vc<Self>

Places a value in a cell of the current task.

Cell is selected based on the value type and call order of cell.

pub fn resolved_cell(self) -> ResolvedVc<Self>

Places a value in a cell of the current task. Returns a ResolvedVc.

Cell is selected based on the value type and call order of cell.

impl Effects

pub async fn apply(&self) -> Result<(), Arc<dyn EffectError>>

Applies all effects that have been captured.

On first call: groups effects by key, detects duplicates/conflicts, caches deduped indices. On subsequent calls: skips grouping (reuses cached indices), only runs per-key state checks.

apply must only be used in a “top-level” task (e.g. run_once), after take_effects is called from an operation read with strong consistency.

See take_effects for example usage.

Trait Implementations

impl Default for Effects

fn default() -> Effects

Returns the “default value” for a type.

impl PartialEq for Effects

fn eq(&self, other: &Self) -> 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 ShrinkToFit for Effects

fn shrink_to_fit(&mut self)

impl TraceRawVcs for Effects

fn trace_raw_vcs(&self, __context__: &mut TraceRawVcsContext)

fn get_raw_vcs(&self) -> Vec<RawVc>

impl ValueDebug for Effects

fn dbg_depth<'a>( &'a self, depth: usize, ) -> Pin<Box<dyn Future<Output = Result<String>> + Send + 'a>>

Like dbg, but with a depth limit.

fn dbg(&self) -> Pin<Box<dyn Future<Output = Result<String>> + Send + '_>>

impl ValueDebugFormat for Effects

Available on debug-assertions enabled only.

fn value_debug_format<'a>(&'a self, depth: usize) -> ValueDebugFormatString<'a>

impl VcValueType for Effects

type Read = VcDefaultRead<Effects>

How to read the value.

type CellMode = VcCellCompareMode<Effects>

How to update cells of this value type.

fn get_value_type_id() -> ValueTypeId

Returns the type id of the value type.

fn has_serialization() -> bool

impl Eq for Effects

impl NonLocalValue for Effects

impl Upcast<Box<dyn ValueDebug>> for Effects

impl UpcastStrict<Box<dyn ValueDebug>> for Effects
