BIMIFC Parser - High-performance IFC parser

This crate provides a fast, memory-efficient parser for IFC (STEP) files. It implements the traits defined in bimifc-model for a clean abstraction.

Features

• Fast tokenization using nom combinators
• SIMD-accelerated scanning using memchr
• Lazy entity decoding - only parse entities when needed
• Arc-based caching - efficient memory sharing
• Progress reporting for large files

Example

use bimifc_parser::StepParser;
use bimifc_model::IfcParser;

let parser = StepParser::new();
let model = parser.parse(ifc_content)?;

// Access entities
let walls = model.resolver().find_by_type_name("IFCWALL");
println!("Found {} walls", walls.len());
