Installation

Add this to your Cargo.toml:

[dependencies]
todoist-api = "0.1.0"

Quick Start

use todoist_api::TodoistWrapper;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create a new Todoist client
    let todoist = TodoistWrapper::new("your-api-token".to_string());
    
    // Get all tasks
    let tasks = todoist.get_tasks().await?;
    println!("Found {} tasks", tasks.len());
    
    // Create a new task
    let new_task = todoist.create_simple_task("Buy groceries", None).await?;
    println!("Created task: {}", new_task.content);
    
    // Complete a task
    todoist.complete_task(&new_task.id).await?;
    println!("Task completed!");
    
    Ok(())
}

• Deadline - Deadline information
• Duration - Task duration tracking

Argument Types

For flexible API operations, the library provides argument types:

• CreateTaskArgs - Full task creation options
• UpdateTaskArgs - Task update parameters
• CreateProjectArgs - Project creation options
• UpdateProjectArgs - Project update parameters
• CreateLabelArgs - Label creation options
• UpdateLabelArgs - Label update parameters

Filter Types

For advanced querying and pagination:

• LabelFilterArgs - Label filtering and pagination
• SectionFilterArgs - Section filtering and pagination
• CommentFilterArgs - Comment filtering and pagination

Error Handling

All operations return anyhow::Result<T>, providing comprehensive error handling:

match todoist.get_tasks().await {
    Ok(tasks) => println!("Found {} tasks", tasks.len()),
    Err(e) => eprintln!("Error fetching tasks: {}", e),
}

Configuration

The library uses sensible defaults:

• 10-second timeout for HTTP requests
• Automatic retry with fallback to default client
• Bearer token authentication
• Comprehensive error handling

Testing

The library includes a comprehensive test suite covering all functionality:

Test Coverage

• Unit Tests: 47 tests covering all models, argument types, and core functionality
• Integration Tests: 10 tests for complete workflows (can be run with real API access)
• ** Documentation Tests**: Ensures all examples compile and run correctly

Running Tests

# Run all tests
cargo test

# Run only unit tests (no API access required)
cargo test --lib

# Run specific test suites
cargo test models_tests
cargo test wrapper_tests
cargo test integration_tests

# Run with verbose output
cargo test -- --nocapture

# Run ignored tests (requires API token)
cargo test -- --ignored

Test Configuration

Set the following environment variables to run integration tests:

export TODOIST_API_TOKEN="your-api-token"
export RUN_INTEGRATION_TESTS=true
