Struct ReducerDef

#[non_exhaustive]
pub struct ReducerDef {
    pub name: Identifier,
    pub params: ProductType,
    pub params_for_generate: ProductTypeDef,
    pub lifecycle: Option<Lifecycle>,
}

A reducer exported by the module.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

name: Identifier

The name of the reducer. This must be unique within the module.

params: ProductType

The parameters of the reducer.

This ProductType need not be registered in the module’s Typespace.

params_for_generate: ProductTypeDef

The parameters of the reducer, formatted for client codegen.

This ProductType need not be registered in the module’s TypespaceForGenerate.

lifecycle: Option<Lifecycle>

The special role of this reducer in the module lifecycle, if any.

Trait Implementations

impl Clone for ReducerDef

fn clone(&self) -> ReducerDef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReducerDef

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

Formats the value using the given formatter.

impl From<ReducerDef> for RawReducerDefV9

fn from(val: ReducerDef) -> Self

Converts to this type from the input type.

impl ModuleDefLookup for ReducerDef

type Key<'a> = &'a Identifier

A reference to a definition of this type within a module def. This reference should be portable across migrations.

fn key(&self) -> Self::Key<'_>

Get a reference to this definition.

fn lookup<'a>(module_def: &'a ModuleDef, key: Self::Key<'_>) -> Option<&'a Self>

Look up this entity in the module def.

impl PartialEq for ReducerDef

fn eq(&self, other: &ReducerDef) -> 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.
