Struct OpenTofuClient 

pub struct OpenTofuClient { /* private fields */ }

A specialized OpenTofu client for infrastructure management. This client provides a consistent interface for OpenTofu operations:

• Initialize OpenTofu configurations
• Plan infrastructure changes
• Apply infrastructure changes
• Destroy infrastructure

Uses CommandExecutor as a collaborator for actual command execution.

Implementations

impl OpenTofuClient

pub fn new<P: Into<PathBuf>>(working_dir: P) -> Self

Creates a new OpenTofuClient

Arguments

• working_dir - Path to the directory containing OpenTofu configuration files

pub fn init(&self) -> Result<String, CommandError>

Initialize OpenTofu configuration

Returns

• Ok(String) - The stdout output if the command succeeds
• Err(CommandError) - Error describing what went wrong

Errors

This function will return an error if:

• The OpenTofu initialization fails
• The working directory does not exist or is not accessible

pub fn validate(&self) -> Result<String, CommandError>

Validate configuration syntax and consistency

Returns

• Ok(String) - The stdout output if the command succeeds
• Err(CommandError) - Error describing what went wrong

Errors

This function will return an error if:

• The OpenTofu validate fails due to syntax or consistency errors
• The configuration is not initialized
• The working directory does not exist or is not accessible

pub fn plan(&self, extra_args: &[&str]) -> Result<String, CommandError>

Plan infrastructure changes

Arguments

• extra_args - Additional arguments to pass to the tofu plan command (e.g., “-var-file=variables.tfvars”)

Returns

• Ok(String) - The stdout output if the command succeeds
• Err(CommandError) - Error describing what went wrong

Errors

This function will return an error if:

• The OpenTofu plan fails
• The configuration is not initialized

pub fn apply( &self, auto_approve: bool, extra_args: &[&str], ) -> Result<String, CommandError>

Apply infrastructure changes

Arguments

• auto_approve - Whether to automatically approve the changes without interactive confirmation
• extra_args - Additional arguments to pass to the tofu apply command (e.g., “-var-file=variables.tfvars”)

Returns

• Ok(String) - The stdout output if the command succeeds
• Err(CommandError) - Error describing what went wrong

Errors

This function will return an error if:

• The OpenTofu apply fails
• The configuration is not initialized

pub fn destroy( &self, auto_approve: bool, extra_args: &[&str], ) -> Result<String, CommandError>

Destroy infrastructure

Arguments

• auto_approve - Whether to automatically approve the destruction without interactive confirmation
• extra_args - Additional arguments to pass to the tofu destroy command (e.g., “-var-file=variables.tfvars”)

Returns

• Ok(String) - The stdout output if the command succeeds
• Err(CommandError) - Error describing what went wrong

Errors

This function will return an error if:

• The OpenTofu destroy fails
• The configuration is not initialized

pub fn get_instance_info(&self) -> Result<InstanceInfo, OpenTofuError>

Get OpenTofu outputs and parse container information

Returns

• Ok(ContainerInfo) - Parsed container information from OpenTofu outputs
• Err(OpenTofuError) - Error describing what went wrong

Errors

This function will return an error if:

• The OpenTofu output command fails
• The output cannot be parsed as JSON
• The instance_info section is missing or malformed

pub fn working_dir(&self) -> &Path

Get the working directory path
