Enum PromotePolicy 

pub enum PromotePolicy {
    KeepKnown,
    Overwrite,
    TrueOnly,
    NonEmpty,
}

How extracted fields are promoted into bare state keys.

Variants

KeepKnown

Write once, never overwrite a known value (default).

Overwrite

Always overwrite.

TrueOnly

Promote only when the extracted value is true.

NonEmpty

Promote only non-empty values.

Trait Implementations

impl Clone for PromotePolicy

fn clone(&self) -> PromotePolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PromotePolicy

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

Formats the value using the given formatter.

impl Default for PromotePolicy

fn default() -> PromotePolicy

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PromotePolicy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for PromotePolicy

fn schema_name() -> String

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 is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl PartialEq for PromotePolicy

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
