How can I add a title and description to an enum's tag key?

[ya7010]

Thanks for the great crate!

I have the following code.

#[derive(Debug, Clone, PartialEq, Eq)]
#[derive(serde::Serialize, serde::Deserialize)]
#[serde(tag = "key")]
#[serde(rename_all = "kebab-case")]
#[derive(schemars::JsonSchema)]
pub enum DataSource {
    /// Format Key?
    Format(FormatInfo),

    /// Lint Key?
    Lint(LintInfo),
}

/// Format Information
#[derive(Debug, Clone, PartialEq, Eq)]
#[derive(serde::Serialize, serde::Deserialize)]
#[derive(schemars::JsonSchema)]
pub struct FormatInfo {
    includes: Vec<String>,
    excludes: Vec<String>,
}

/// Lint Information
#[derive(Debug, Clone, PartialEq, Eq)]
#[derive(serde::Serialize, serde::Deserialize)]
#[derive(schemars::JsonSchema)]
pub struct LintInfo {
    includes: Vec<String>,
    excludes: Vec<String>,
}

Output Schema:

{
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "title": "DataSource",
  "oneOf": [
    {
      "description": "Format Key?",
      "type": "object",
      "properties": {
        "key": {
          // I want to "title" and "description" here
          "type": "string",
          "const": "format"
        }
      },
      "$ref": "#/$defs/FormatInfo",
      "required": [
        "key"
      ]
    },
    {

      "properties": {
        "key": {
          // I want to "title" and "description" here
          "type": "string",
          "const": "lint"
        }
      },
      "$ref": "#/$defs/LintInfo",
      "required": [
        "key"
      ]
    }
  ],
  "$defs": {
    "FormatInfo": {
      "description": "Format Information",
      "type": "object",
      "properties": {
        "excludes": {
          "type": "array",
          "items": {
            "type": "string"
          }
        },
        "includes": {
          "type": "array",
          "items": {
            "type": "string"
          }
        }
      },
      "required": [
        "includes",
        "excludes"
      ]
    },
    "LintInfo": {
      "description": "Lint Information",
      "type": "object",
      "properties": {
        "excludes": {
          "type": "array",
          "items": {
            "type": "string"
          }
        },
        "includes": {
          "type": "array",
          "items": {
            "type": "string"
          }
        }
      },
      "required": [
        "includes",
        "excludes"
      ]
    }
  }
}

Is there a way to add title and description properties to the "key" property?
