Struct TemplateRenderer 

pub struct TemplateRenderer { /* private fields */ }

Template renderer with Tera engine

Provides template rendering with custom functions for:

• Environment variable access
• Deterministic timestamps
• SHA-256 hashing
• TOML encoding
• Macro library for common TOML patterns

Implementations

impl TemplateRenderer

pub fn new() -> Result<Self>

Create new template renderer with custom functions and macro library

pub fn with_defaults() -> Result<Self>

Create renderer with default PRD v1.0 variable resolution

Initializes context with standard variables resolved via precedence: template vars → ENV → defaults

pub fn with_context(self, context: TemplateContext) -> Self

Set template context variables

pub fn merge_user_vars(&mut self, user_vars: HashMap<String, Value>)

Merge user-provided variables into context (respects precedence)

User variables take highest priority in the precedence chain

pub fn render_file(&mut self, path: &Path) -> Result<String>

Render template file to TOML string

pub fn render_str(&mut self, template: &str, name: &str) -> Result<String>

Render template string to TOML

pub fn render_from_glob( &mut self, glob_pattern: &str, template_name: &str, ) -> Result<String>

Render template from glob pattern

Useful for rendering multiple templates with shared context
