Function fromZoirNodeAlloc [src]

Like fromZoirAlloc, but the parse starts at node instead of root.

Prototype

 pub fn fromZoirNodeAlloc( T: type, gpa: Allocator, ast: Ast, zoir: Zoir, node: Zoir.Node.Index, diag: ?*Diagnostics, options: Options, ) error{ OutOfMemory, ParseZon }!T

Parameters

T: typegpa: Allocatorast: Astzoir: Zoirnode: Zoir.Node.Indexdiag: ?*Diagnosticsoptions: Options

Possible Errors

OutOfMemory

ParseZon

        s.zoir = zoir;
    }

    if (zoir.hasCompileErrors()) {

    var parser: Parser = .{

        .ast = ast,
        .zoir = zoir,
        .options = options,
        .diag = diag,
    };

    return parser.parseExpr(T, node);
}
