How to auto generate references for enum variants

[universalmind303]

Is there any way to force schemars to use references for enum variants? When inlining, many tools can't recognize the title or description for that object, and just shows up as (object).

For example.

pub enum StringExpr {
    #[serde(rename = "$starts_with")]
    StartsWith(String),
    #[serde(rename = "$ends_with")]
    EndsWith(String),
}

and this will generate something like this:

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "title": "StringExpr",
  "oneOf": [
    {
      "type": "object",
      "required": [
        "$starts_with"
      ],
      "properties": {
        "$starts_with": {
          "type": "string"
        }
      },
      "additionalProperties": false
    },
    {
      "type": "object",
      "required": [
        "$ends_with"
      ],
      "properties": {
        "$ends_with": {
          "type": "string"
        }
      },
      "additionalProperties": false
    }
  ]
}

But what would be preferred is if there was some way to make all of those inner objects references by default.

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "title": "StringExpr",
  "examples": [
    {
      "$starts_with": "bar"
    }
  ],
  "oneOf": [
    {
      "$ref": "#/definitions/StringExpr/starts_with"
    },
    {
      "$ref": "#/definitions/StringExpr/ends_with"
    }
  ],
  "definitions": {
    "StringExpr": {
      "starts_with": {
        "type": "object",
        "required": [
          "$starts_with"
        ],
        "properties": {
          "$starts_with": {
            "type": "string"
          }
        },
        "additionalProperties": false
      },
      "ends_with": {
        "type": "object",
        "required": [
          "$ends_with"
        ],
        "properties": {
          "$ends_with": {
            "type": "string"
          }
        },
        "additionalProperties": false
      }
    }
  }
}
