Example JSON format

[
  {
    "name": "count",
    "type_name": "i32",
    "is_nested": false,
    "children": []
  },
  {
    "name": "user",
    "type_name": "User",
    "is_nested": true,
    "children": [
      {"name": "name", "type_name": "String", "is_nested": false, "children": []},
      {"name": "email", "type_name": "String", "is_nested": false, "children": []}
    ]
  }
]

pub fn contains_field(&self, path: &[&str]) -> bool

Checks if a field path exists in the model.

Arguments

• path - Slice of field names representing the path (e.g., &[“user”, “name”])

Returns

true if the field path exists, false otherwise.

pub fn top_level_fields(&self) -> Vec<&str>

Gets all top-level field names.

Returns

A vector of all top-level field names.

pub fn all_field_paths(&self) -> Vec<String>

pub fn add_field(&mut self, field: ModelField)

Adds a field to the model.

pub fn len(&self) -> usize

Gets the number of top-level fields.

pub fn is_empty(&self) -> bool
