Struct ParamMeta 

pub struct ParamMeta {
    pub name: &'static str,
    pub source: &'static str,
    pub type_hint: &'static str,
    pub required: bool,
    pub json_key: Option<&'static str>,
}

Metadata about a request parameter for OpenAPI generation.

Fields

name: &'static str

Field name (e.g., “id”, “body”).

source: &'static str

Parameter location: “path”, “query”, “header”, “form”, “body”, “claim”, or “” for an unmarked field that the route method resolves.

type_hint: &'static str

Type hint for OpenAPI schema (e.g., “string”, “integer”, “object”).

required: bool

Whether the parameter must be present (Option<T> and Vec<T> are not required; path parameters always are).

json_key: Option<&'static str>

The JSON object key this parameter binds from, when it can bind from a JSON body: an explicit #[frombody] field, a composite field, or an unmarked field on a write method (the route method decides; source is "" for those).

None for parameters bound from the path, query, header, form or claims, and for a body field with no JSON key of its own — a #[serde(flatten)] field spreads its inner properties into the body object instead of owning one key.
