🎯 Features Added​

Validator​

✅ Basic Validators:

  • starts_with(prefix) - Check if message starts with prefix
  • ends_with(suffix) - Check if message ends with suffix
  • contains(substring) - Check if message contains substring
  • regex(pattern) - Match against regex pattern

✅ Logical Combinators:

  • ne(validator) - Negate a validator (NOT)
  • all(validators) - All validators must match (AND)
  • any(validators) - At least one validator must match (OR)

✅ Instance Method:

  • check(message) - Test if message matches validator

Raw Handler​

✅ Send Methods:

  • send_text(message) - Send text message
  • send_binary(data) - Send binary message
  • send_and_wait(message) - Send and wait for response

✅ Receive Methods:

  • wait_next() - Wait for next matching message

✅ Keep-Alive:

  • Optional keep-alive parameter for automatic reconnection

Payout​

✅ New Method:

  • payout(asset) - Get profit percentage for an asset

💻 Code Examples​

Python Example​

import asyncio
from binaryoptionstoolsuni import PocketOption, Validator

async def main():
    client = await PocketOption.init("your_ssid")
    await asyncio.sleep(2)

    # Create validator for balance messages
    validator = Validator.contains('"balance"')

    # Create raw handler
    handler = await client.create_raw_handler(validator, None)

    # Send custom message
    await handler.send_text('42["getBalance"]')

    # Wait for response
    response = await handler.wait_next()
    print(f"Response: {response}")

    # Get payout for asset
    payout = await client.payout("EURUSD_otc")
    print(f"Payout: {payout * 100}%")

    await client.shutdown()

asyncio.run(main())

Kotlin Example​

import com.chipadevteam.binaryoptionstoolsuni.*
import kotlinx.coroutines.*

suspend fun main() = coroutineScope {
    val client = PocketOption.init("your_ssid")
    delay(2000)

    // Create validator
    val validator = Validator.contains("\"balance\"")

    // Create raw handler
    val handler = client.createRawHandler(validator, null)

    // Send and receive
    handler.sendText("42[\"getBalance\"]")
    val response = handler.waitNext()
    println("Response: $response")

    // Get payout
    val payout = client.payout("EURUSD_otc")
    println("Payout: ${payout?.times(100)}%")

    client.shutdown()
}

Swift Example​

import BinaryOptionsToolsUni

Task {
    let client = try await PocketOption.init(ssid: "your_ssid")
    try await Task.sleep(nanoseconds: 2_000_000_000)

    // Create validator
    let validator = Validator.contains(substring: "\"balance\"")

    // Create raw handler
    let handler = try await client.createRawHandler(
        validator: validator,
        keepAlive: nil
    )

    // Send and receive
    try await handler.sendText(message: "42[\"getBalance\"]")
    let response = try await handler.waitNext()
    print("Response: \(response)")

    // Get payout
    if let payout = await client.payout(asset: "EURUSD_otc") {
        print("Payout: \(payout * 100)%")
    }

    try await client.shutdown()
}

🔍 API Comparison​

Python vs UniFFI​

FeaturePython APIUniFFI APIStatus
Validator.starts_with✅✅Same
Validator.ends_with✅✅Same
Validator.contains✅✅Same
Validator.regex✅✅Same
Validator.ne✅✅Same
Validator.all✅✅Same
Validator.any✅✅Same
Validator.custom✅❌Not supported (FFI limitation)
RawHandler.send_text✅✅Same
RawHandler.send_binary✅✅Same
RawHandler.send_and_wait✅✅Same
RawHandler.wait_next✅✅Same
Keep-alive support✅✅Same
Payout method✅✅Same

Note: Custom validators (using Python functions) are not supported in UniFFI because they require calling Python functions from Rust, which is complex and not currently supported by UniFFI.

📊 Use Cases​

1. Custom Message Monitoring​

# Monitor specific message types
validator = Validator.all([
    Validator.starts_with("42["),
    Validator.contains('"type":"candle"')
])
handler = await client.create_raw_handler(validator, None)

2. Low-Level Protocol Implementation​

# Implement custom protocols on top of WebSocket
async def send_custom_command(handler, command, args):
    message = json.dumps([command, args])
    response = await handler.send_and_wait(message)
    return json.loads(response)

3. Debugging and Logging​

# Log all messages containing errors
error_validator = Validator.contains("error")
error_handler = await client.create_raw_handler(error_validator, None)

while True:
    error_msg = await error_handler.wait_next()
    print(f"ERROR: {error_msg}")

4. Multiple Subscriptions​

# Handle different message types with different handlers
balance_handler = await client.create_raw_handler(
    Validator.contains("balance"), None
)
trade_handler = await client.create_raw_handler(
    Validator.contains("trade"), None
)
