Struct FileBuilder 

pub struct FileBuilder {
    pub imports: ImportCollector,
    pub code: CodeBuilder,
}

Composable file builder that combines import collection with code generation.

This struct provides a language-agnostic way to build source files that need both imports and code. Language-specific crates can add rendering methods.

Example

use baobao_codegen::{FileBuilder, Indent};

let mut builder = FileBuilder::new(Indent::RUST);
builder.imports.add("std::io", "Read");
builder.code = builder.code.line("fn main() {}");

// Language-specific rendering would be added by extension

Fields

imports: ImportCollector

Import collector for tracking dependencies

code: CodeBuilder

Code builder for generating the file body
