Trait ExtensionInfo 

pub trait ExtensionInfo: Clone + 'static {
    const ID: &'static str;

    // Required method
    fn schema() -> Value;
}

Trait for typed extension info with compile-time schema generation.

Implement this trait for your extension’s info type to enable:

• Type-safe extension construction via Extension::typed
• Automatic schema generation via ExtensionInfo::schema
• Automatic key assignment via ExtensionInfo::ID

Example

use serde::{Serialize, Deserialize};
use x402_core::types::{ExtensionInfo, AnyJson};
use serde_json::json;

#[derive(Debug, Clone, Serialize, Deserialize)]
struct MyInfo {
    pub value: String,
}

impl ExtensionInfo for MyInfo {
    const ID: &'static str = "my-extension";
    fn schema() -> AnyJson {
        json!({
            "type": "object",
            "properties": {
                "value": { "type": "string" }
            },
            "required": ["value"]
        })
    }
}

Required Associated Constants

const ID: &'static str

The extension identifier, used as the key in the extensions map.

Required Methods

fn schema() -> Value

Generate a JSON Schema for this extension’s info type.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl ExtensionInfo for BazaarInfo

const ID: &'static str = "bazaar"

impl ExtensionInfo for SignInWithXInfo

const ID: &'static str = "sign-in-with-x"
