Function render_template 

pub fn render_template(
    main_typ: String,
    file_system: Arc<dyn RenderFileSystem>,
    data: &Value,
) -> Result<RenderResult>

Render a Typst template to PDF

This is the main public API for template compilation. It takes a template string, a file system for resolving imports, and JSON data to inject into the template.

Arguments

• main_typ - The main Typst template content as a string
• file_system - File system abstraction for resolving imports and assets
• data - JSON data to inject into the template

Returns

Returns a RenderResult containing either the PDF bytes (on success) or detailed error information (on failure).

Errors

This function can return various errors:

• DataError - JSON serialization issues
• CompilationError - Typst compilation failures
• FileSystemError - File access issues during import resolution

Example

use papermake::{render_template, typst::InMemoryFileSystem};
use std::sync::Arc;

let template = "Hello #data.name!";
let fs = Arc::new(InMemoryFileSystem::new());
let data = serde_json::json!({ "name": "World" });

let result = render_template(template.to_string(), fs, &data).unwrap();
if result.success {
    println!("PDF generated: {} bytes", result.pdf.unwrap().len());
} else {
    for error in result.errors {
        println!("Error: {}", error);
    }
}
