ptx-syntax-proc-macros

ptx-syntax-proc-macros contains the procedural macros used to implement ptx-syntax. It is an implementation dependency rather than a standalone parsing API.

The crate provides:

• c! – construct a struct and automatically fill its span field.
• ok! / err! – convenience constructors for Result-producing parser code.
• cclosure! / okmap! – turn tuples of parser outputs into AST values while threading spans.
• func! – append a span argument to an existing closure.
• #[derive(Spanned)] – implement the parser's Spanned trait for an AST struct or enum containing a named span field.

use ptx_syntax_proc_macros::{c, ok};

fn parse_operand(symbol: Symbol, span: Span) -> Result<Operand, PtxParseError> {
    ok!(Operand::Symbol { symbol })
}
