Struct TemplateManager 

pub struct TemplateManager { /* private fields */ }

Template manager that handles on-demand creation of templates from embedded resources

Implementations

impl TemplateManager

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

Create a new template manager with a custom templates directory

pub fn ensure_templates_dir(&self) -> Result<(), TemplateManagerError>

Create the templates directory if it doesn’t exist

Errors

Returns an error if the directory creation fails due to permissions or filesystem issues.

pub fn reset_templates_dir(&self) -> Result<(), TemplateManagerError>

Clean and prepare the templates directory to ensure fresh embedded templates

This method combines clean_templates_dir() and ensure_templates_dir() to provide a clean state for template operations. It’s particularly useful in testing and development environments where you want to ensure fresh templates from embedded resources.

Errors

Returns an error if either directory cleaning or creation fails due to permissions or filesystem issues.

pub fn get_template_path( &self, relative_path: &str, ) -> Result<PathBuf, TemplateManagerError>

Get the path to a template file, creating it from embedded resources if it doesn’t exist

Errors

Returns an error if:

• The template is not found in embedded resources
• The embedded template contains invalid UTF-8
• File system operations fail (directory creation or file writing)

pub fn templates_dir(&self) -> &Path

Get the templates directory path

pub fn clean_templates_dir(&self) -> Result<(), TemplateManagerError>

Clean the templates directory by removing all files and subdirectories

This is useful for development/testing to ensure fresh templates are used from embedded resources.

Errors

Returns an error if the directory removal fails due to permissions or filesystem issues.
