[Question] How to access jsonSchema elements from template

Question...
Is there a syntax that allows accessing a generic JSON element in a variable(jsonSchema) ?

I'm generating rust code and are having problems accessing some values...
Given the following yaml:

components:
  schemas:
    formEditSettingsNewUserGroup: # $ref: '#/components/schemas/formEditSettingsNewUserGroup'
      description: Create a new user Group
      type: object
      properties:
          name_:          
            type: string
            nullable: false
            description: New Group name
            example: NewGroupName
          isadmingroup_:
            description: Is Admin Group [0 - No, 1 - yes]
            nullable: false
            type: string
            enum:
              - 0
              - 1
            default:  0

---------  template[model.mustache.mustache]: --------- 
...
impl Default for {{{classname}}} {
    fn default() -> Self {
        Self {
{{#vars}}/* {{{.}}} */
{{>partial_var_name_default}}
{{/vars}}
            _extra_fields: HashMap::new(),
            ..Default::default()
        }
    }
}
--------- template[partial_var_name_default.mustache]: --------- 
        {{{name}}} : {{#defaultValue}}{{^required}}Some({{/required}}{{#isString}}{{#isEnum}}{{{datatypeWithEnum}}}::default(){{/isEnum}}{{^isEnum}}String::from("{{defaultValue}}"){{/isEnum}}{{/isString}}{{^isString}}{{defaultValue}}{{/isString}}{{^required}}){{/required}},
        {{/defaultValue}}{{^defaultValue}}{{^required}}None{{/required}}{{#required}}{{#isString}}String::from(""){{/isString}}{{#isInteger}}-1{{/isInteger}}{{#isLong}}-1{{/isLong}}{{#isFloat}}f32::NAN{{/isFloat}}{{#isDouble}}f64::NAN{{/isDouble}}{{/required}},{{/defaultValue}}
---------

I'm trying to access the Default value, it workds great, except for enums...
the default value is: [defaultValue='Isadmingroup__0' ]
which is not correct. if anything, in rust it should be:
[defaultValue='Isadmingroup_::_0' ]

the only place is it the text value is in the jsonSchema
jsonSchema='{
"type" : "string",
"description" : "Is Admin Group [0 - No, 1 - yes]",
"nullable" : false,
"default" : "0",
"enum" : [ "0", "1" ]

is there some syntax that allows access to the JSON elements ?
I've tried all permutations...
{{#jsonSchema}}{{{.}}}{{/jsonSchema}} yeilds the above

{{#jsonSchema}}{{#default}}{{{.}}}{{/default}}{{/jsonSchema}} yeilds nothing

what is the correct syntax for accessing "jsonSchema.default"

Output of template element

Start with the Rust generator templates model.mustache.mustache and partial_var_name_default.mustache, then inspect how the jsonSchema and defaultValue fields are exposed to Mustache. Compare the template context with the generated Rust output shown in the issue. Done means documenting the supported syntax for accessing the schema default, or clarifying the required template/model change.
