Function disassemble_from_str_unchecked 

pub fn disassemble_from_str_unchecked<N: Network>(
    name: impl Display,
    program: &str,
) -> Result<AleoProgram, LeoError>

Parse-only disassembly. Performs grammar-level checks via Program::from_str and converts to the leo AST. Prefer disassemble_from_str (native) if you have a Process and want the snarkVM semantic checks that reject the class of malformed-but-parseable bytecode that disassemble panics on; this _unchecked variant skips that step.
