Struct ViewDef 

pub struct ViewDef {
    pub id: String,
    pub source: ViewSource,
    pub pipeline: Vec<ViewTransform>,
    pub output: ViewOutput,
}

Definition of a view in the pipeline

Fields

id: String

Unique view identifier (e.g., “OreRound/latest”)

source: ViewSource

Source this view derives from

pipeline: Vec<ViewTransform>

Pipeline of transforms to apply (in order)

output: ViewOutput

Output mode for this view

Implementations

impl ViewDef

pub fn list(entity_name: &str) -> Self

Create a new list view for an entity

pub fn state(entity_name: &str, key_field: &[&str]) -> Self

Create a new state view for an entity

pub fn is_single(&self) -> bool

Check if this view produces a single entity

pub fn has_single_transform(&self) -> bool

Check if any transform in the pipeline produces a single result

Trait Implementations

impl Clone for ViewDef

fn clone(&self) -> ViewDef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ViewDef

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ViewDef

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ViewDef

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
