Derive Macro JsonSchema 

#[derive(JsonSchema)]
{
    // Attributes available to this derive:
    #[serde]
}

Available on crate feature macros only.

Derive rust_web_server::schema::JsonSchema for a struct with named fields or an enum of unit variants.

The schema follows the type’s serde attributes, so it describes the JSON serde_json reads and writes: container rename_all and default; field rename, default, skip/skip_serializing/skip_deserializing (left out) and skip_serializing_if (not required); variant rename. Attributes that change the JSON’s shape — flatten, tag, content, untagged, transparent, with/serialize_with/deserialize_with, separate serialize/deserialize renames — are a compile error rather than a schema that doesn’t match. Option fields are not required. Doc comments become descriptions.

#[derive(serde::Serialize, serde::Deserialize, rust_web_server::JsonSchema)]
#[serde(rename_all = "camelCase")]
struct Item {
    /// Stock keeping unit.
    sku: String,
    in_stock: u32,
    note: Option<String>,
}
