Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl Condition

pub fn children(&self) -> impl Iterator<Item = &Condition>

Iterator over this node’s direct child conditions.

pub fn walk<'a>(&'a self, visitor: &mut impl FnMut(&'a Condition))

Visits every node in the tree (pre-order), iteratively to avoid stack overflow on WASM.

pub fn walk_with_depth<'a>( &'a self, visitor: &mut impl FnMut(&'a Condition, usize), )

Visits every node and its one-based depth in pre-order.

pub fn field_reads(&self) -> Vec<&FieldRead>

Collects every FieldRead leaf in the tree.

Trait Implementations

impl Clone for Condition

fn clone(&self) -> Condition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Condition

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Condition

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Condition> for JsValue

where Condition: Serialize,

fn from(value: Condition) -> Self

Converts to this type from the input type.

impl FromWasmAbi for Condition

where Self: DeserializeOwned,

type Abi = <JsType as FromWasmAbi>::Abi

The Wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: Self::Abi) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for &Condition

where Condition: Serialize,

type Abi = <JsType as IntoWasmAbi>::Abi

The Wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> Self::Abi

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl IntoWasmAbi for Condition

where Condition: Serialize,

type Abi = <JsType as IntoWasmAbi>::Abi

The Wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> Self::Abi

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl JsonSchema for Condition

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl OptionFromWasmAbi for Condition

where Self: DeserializeOwned,

fn is_none(js: &Self::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for Condition

where Condition: Serialize,

fn none() -> Self::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl PartialEq for Condition

fn eq(&self, other: &Condition) -> 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 RefFromWasmAbi for Condition

where Self: DeserializeOwned,

type Abi = <JsType as RefFromWasmAbi>::Abi

The Wasm ABI type references to Self are recovered from.

type Anchor = SelfOwner<Condition>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.

unsafe fn ref_from_abi(js: Self::Abi) -> Self::Anchor

Recover a Self::Anchor from Self::Abi.

impl Serialize for Condition

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Tsify for Condition

const DECL: &'static str = "/**\n * Composable condition tree used by authored rotations.\n */\nexport type Condition = ({ type: \"read\" } & {} & FieldRead) | { type: \"bool\"; value: boolean } | { type: \"int\"; value: number } | { type: \"float\"; value: number } | { type: \"var\"; name: string } | { type: \"compare\"; op: CompareOp; left: Condition; right: Condition } | { type: \"and\"; operands: Condition[] } | { type: \"or\"; operands: Condition[] } | { type: \"not\"; operand: Condition } | { type: \"arith\"; op: ArithOp; left: Condition; right: Condition } | { type: \"unary_math\"; op: UnaryMathOp; operand: Condition } | { type: \"min_max\"; op: MinMaxOp; left: Condition; right: Condition } | { type: \"if_then_else\"; condition: Condition; then: Condition; otherwise: Condition };"
