Struct CParser 

pub struct CParser { /* private fields */ }

C parser using clang-sys.

Examples

use decy_parser::parser::CParser;

let parser = CParser::new()?;
let ast = parser.parse("int main() { return 0; }")?;
assert_eq!(ast.functions().len(), 1);

Implementations

impl CParser

pub fn new() -> Result<Self>

Create a new C parser.

This automatically discovers system include paths from the clang compiler.

Examples

use decy_parser::parser::CParser;

let parser = CParser::new()?;

pub fn parse(&self, source: &str) -> Result<Ast>

Parse C source code into an AST.

Arguments

• source - The C source code to parse

Returns

• Ok(Ast) - The parsed AST
• Err(anyhow::Error) - If parsing fails

Examples

use decy_parser::parser::CParser;

let parser = CParser::new()?;
let ast = parser.parse("int add(int a, int b) { return a + b; }")?;

pub fn parse_file(&self, path: &Path) -> Result<Ast>

Parse a C file into an AST.

Arguments

• path - Path to the C file

Returns

• Ok(Ast) - The parsed AST
• Err(anyhow::Error) - If parsing fails

Parse C source code from a file path.

DECY-237: This method allows includes to resolve properly by parsing from the actual file path instead of an in-memory string.

Trait Implementations

impl Debug for CParser

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

Formats the value using the given formatter.

impl Drop for CParser

fn drop(&mut self)

Executes the destructor for this type.
