fromZoirNode

Like fromZoir, but the parse starts on node instead of root.

Function parameters

Parameters

T:type
gpa:Allocator
ast:Ast
zoir:Zoir
node:Zoir.Node.Index
diag:?*Diagnostics
options:Options

Configuration for the runtime parser.

Types

Options: Configuration for the runtime parser.
Error
Diagnostics: Information about the success or failure of a parse.

Parses the given slice as ZON.

Functions

fromSlice: Parses the given slice as ZON.
fromZoir: Like `fromSlice`, but operates on `Zoir` instead of ZON source.
fromZoirNode: Like `fromZoir`, but the parse starts on `node` instead of root.
free: Frees ZON values.

Implementation

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

    if (diag) |s| {
        s.assertEmpty();
        s.ast = ast;
        s.zoir = zoir;
    }

    if (zoir.hasCompileErrors()) {
        return error.ParseZon;
    }

    var parser: Parser = .{
        .gpa = gpa,
        .ast = ast,
        .zoir = zoir,
        .options = options,
        .diag = diag,
    };

    return parser.parseExpr(T, node);
}
