Zig 0.17.0-dev (Split by item)

This is an example of documentation generated by ZigDoc, an alternative to Zig's built-in Auto Doc feature. See also examples in other modes/formats. The project being documented here (as the example) is the Zig library itself.

parseFromValue

Like parseFromSlice, but the input is an already-parsed std.json.Value object. Only options.ignore_unknown_fields is used from options.

static.parseFromValue

pub fn parseFromValue(
    comptime T: type,
    allocator: Allocator,
    source: Value,
    options: ParseOptions,
) ParseFromValueError!Parsed(T)

Code

pub fn parseFromValue(
    comptime T: type,
    allocator: Allocator,
    source: Value,
    options: ParseOptions,
) ParseFromValueError!Parsed(T) {
    var parsed = Parsed(T){
        .arena = try allocator.create(ArenaAllocator),
        .value = undefined,
    };
    errdefer allocator.destroy(parsed.arena);
    parsed.arena.* = ArenaAllocator.init(allocator);
    errdefer parsed.arena.deinit();

    parsed.value = try parseFromValueLeaky(T, parsed.arena.allocator(), source, options);

    return parsed;
}
