Struct ValidateCommandHandler 

pub struct ValidateCommandHandler;

Application layer handler for validate command

This handler validates environment configuration files by:

1. Parsing the JSON structure
2. Validating field types and values
3. Verifying referenced files exist (SSH keys)
4. Checking domain constraints

Implementations

impl ValidateCommandHandler

pub fn new() -> Self

Create a new validate command handler

pub fn validate( &self, config_path: &Path, ) -> Result<ValidationResult, ValidateCommandHandlerError>

Validate an environment configuration file

This method performs comprehensive validation:

• JSON syntax and structure
• Field types and constraints
• SSH key file existence
• Domain business rules

Arguments

• config_path - Path to the configuration file to validate

Returns

• Ok(ValidationResult) - Configuration is valid with details
• Err(ValidateCommandHandlerError) - Validation failed with specific reason

Errors

Returns an error if:

• File cannot be read
• JSON syntax is invalid
• Required fields are missing
• Field values violate constraints
• Referenced SSH keys don’t exist
• Domain rules are violated

Examples

use std::path::Path;
use torrust_tracker_deployer_lib::application::command_handlers::validate::ValidateCommandHandler;

let handler = ValidateCommandHandler::new();
let result = handler.validate(Path::new("envs/my-env.json"))?;

println!("Configuration is valid!");
println!("Environment name: {}", result.environment_name);
