Struct FormatProxy 

pub struct FormatProxy {
    pub format: &'static str,
    pub proxy: &'static ProxyDef,
}

A format-specific proxy definition.

This associates a format namespace (like “xml” or “json”) with a proxy definition. Used to support #[facet(xml::proxy = XmlWrapper)] style attributes where different formats need different proxy types for the same field or container.

Resolution order

When serializing/deserializing, proxies are resolved in this order:

1. Format-specific proxy (e.g., xml::proxy when deserializing XML)
2. Format-agnostic proxy (proxy)
3. Normal serialization/deserialization (no proxy)

Example

#[derive(Facet)]
struct MyType {
    #[facet(xml::proxy = XmlParameterProxy)]
    #[facet(json::proxy = JsonParameterProxy)]
    #[facet(proxy = DefaultProxy)]  // fallback for other formats
    parameter: Parameter,
}

Fields

format: &'static str

The format namespace (e.g., “xml”, “json”).

proxy: &'static ProxyDef

The proxy definition for this format.
