Struct MergePropertiesIntoOneOf 

pub struct MergePropertiesIntoOneOf;

A schemars Transform that merges top-level properties and required fields from a wrapper struct into each oneOf variant.

This is used when a struct wraps a #[serde(flatten)] tagged enum: schemars places the struct’s own fields as top-level properties alongside the enum’s oneOf. OpenAPI code generators don’t handle this combination, so this transform pushes the shared properties into each variant so they appear in the generated models.

Usage

#[derive(schemars::JsonSchema, serde::Serialize, serde::Deserialize)]
#[serde(rename_all = "camelCase")]
#[schemars(transform = MergePropertiesIntoOneOf)]
struct Wrapper {
    sequence_number: u64,
    timestamp: DateTime<Utc>,
    #[serde(flatten)]
    kind: MyEnum,
}
