Function enforce_nesting_depth 

pub fn enforce_nesting_depth(
    schema: &mut Value,
    max_depth: usize,
    current: usize,
)

Enforces a maximum nesting depth for object schemas.

Tracks nesting depth through object schemas. When current >= max_depth, replaces the schema with {"type": "object"} and emits a tracing::warn!() log. Recurses into properties/items/etc, incrementing depth for object schemas.

Arguments

• schema - The schema to enforce depth on.
• max_depth - Maximum allowed nesting depth.
• current - Current depth (start at 0).

Example

use serde_json::json;
use adk_core::schema_utils::enforce_nesting_depth;

let mut schema = json!({
    "type": "object",
    "properties": {
        "level1": {
            "type": "object",
            "properties": {
                "level2": { "type": "string" }
            }
        }
    }
});

enforce_nesting_depth(&mut schema, 1, 0);
// level1 is at depth 1, so it gets replaced
assert_eq!(schema["properties"]["level1"], json!({"type": "object"}));
