Struct glib::variant::DictEntry

source ·
pub struct DictEntry<K, V> { /* private fields */ }
Expand description

A Dictionary entry.

While GVariant format allows a dictionary entry to be an independent type, typically you’ll need to use this in a dictionary, which is simply an array of dictionary entries. The following code creates a dictionary:

use glib::{Variant, FromVariant, ToVariant};
use glib::variant::DictEntry;

let entries = [
    DictEntry::new("uuid", 1000u32),
    DictEntry::new("guid", 1001u32),
];
let dict = entries.into_iter().collect::<Variant>();
assert_eq!(dict.n_children(), 2);
assert_eq!(dict.type_().as_str(), "a{su}");
