Function toDot [src]

Prototype

pub fn toDot(self: Oid, writer: anytype) @TypeOf(writer).Error!void

Parameters

self: Oid

Example

 test toDot {
    var buf: [256]u8 = undefined;

    for (test_cases) |t| {
        var stream = std.io.fixedBufferStream(&buf);
        try toDot(Oid{ .encoded = t.encoded }, stream.writer());
        try std.testing.expectEqualStrings(t.dot_notation, stream.getWritten());
    }
}
