Struct Preprocessor 

pub struct Preprocessor { /* private fields */ }

Preprocessor state.

Implementations

impl Preprocessor

pub fn new() -> Self

Create a new preprocessor.

pub fn set_max_recursion_depth(&mut self, depth: usize)

Set the maximum recursion depth for macro expansion.

pub fn set_max_iterations(&mut self, count: usize)

Set the maximum total iteration count for .rept/.irp/.irpc.

pub fn define_symbol(&mut self, name: &str, value: i128)

Define a symbol for conditional assembly.

pub fn process<'a>(&mut self, source: &'a str) -> Result<Cow<'a, str>, AsmError>

Process source text, expanding all preprocessor directives.

Returns the expanded source text ready for lexing/parsing. When no preprocessor directives are present and no macros are defined, returns a borrowed reference to the original source (zero allocation).

Errors

Returns AsmError on malformed directives, recursion limit, or iteration limit exceeded.

Trait Implementations

impl Debug for Preprocessor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Preprocessor

fn default() -> Self

Returns the “default value” for a type.
