Bagaimana cara mendapatkan id posting jenis posting kustom dari slug?

if ( $post = get_page_by_path( 'the_slug', OBJECT, 'post_type' ) )
    $id = $post->ID;
else
    $id = 0;

$args = [
    'post_type'      => 'my_custom_post_type',
    'posts_per_page' => 1,
    'post_name__in'  => ['post-slug']
];
$q = get_posts( $args );
var_dump( $q );

$args = [
    'post_type'      => 'my_custom_post_type',
    'posts_per_page' => 1,
    'post_name__in'  => ['post-slug'],
    'fields'         => 'ids' 
];
$q = get_posts( $args );
var_dump( $q );

url_to_postid( site_url('the_slug') );
