Struct ParseResult 

pub struct ParseResult {
    pub program: Program<'static>,
    pub allocator: Allocator,
    pub errors: Vec<String>,
    pub file_path: String,
}

Result of parsing a TypeScript source file

CRITICAL FIX FOR SEGFAULT: The Program has ’static lifetime via safe transmute. ParseResult owns BOTH the Program AND the Allocator, ensuring they’re dropped together.

The ORIGINAL segfault occurred when code did: let mut program = parse_result.program; // Moves Program out! Transformer::transform(&parse_result.allocator, …); // parse_result dropped here -> allocator freed -> program is dangling!

THE FIX in Compiler.rs - NEVER move Program out: let program = &mut parse_result.program; // Borrow mutably Transformer::transform(&parse_result.allocator, program, …); // parse_result stays in scope -> allocator stays alive -> no segfault!

Fields

program: Program<'static>

The parsed AST program with ’static lifetime (safe transmute)

allocator: Allocator

The allocator used for the AST - owns the memory for the Program CRITICAL: Must not be dropped separately from program

errors: Vec<String>

Any parsing errors encountered

file_path: String

File path for debugging
