Struct DownloadDiskUsage 

pub struct DownloadDiskUsage {
    pub sizes: HashMap<String, i64>,
    pub partial_containers: HashMap<String, bool>,
    pub device_total_bytes: i64,
    pub item_count: u32,
}

On-disk usage of downloaded content, for the Downloads surface.

sizes maps an item id (leaf or container) to its bytes on disk: a leaf’s own file size, a container’s summed downloaded descendants. device_total_bytes and item_count are the headline figures for the Downloaded surface top bar.

TRACES: UR-056 | DR-085

Fields

sizes: HashMap<String, i64>

item id → bytes on disk (leaf’s own size, or a container’s subtotal).

partial_containers: HashMap<String, bool>

Container id → true when it is only partially downloaded (has cached children that are not downloaded). Absent/false ⇒ fully downloaded. Lets the Downloaded surface badge partial vs. full containers.

device_total_bytes: i64

Sum of all downloaded leaf sizes — the device total.

item_count: u32

Number of downloaded leaf items (not containers).

Trait Implementations

impl Clone for DownloadDiskUsage

fn clone(&self) -> DownloadDiskUsage

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DownloadDiskUsage

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DownloadDiskUsage

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl NamedType for DownloadDiskUsage

fn sid() -> SpectaID

fn named_data_type( type_map: &mut TypeCollection, generics: &[DataType], ) -> NamedDataType

this is equivalent to [Type::inline] but returns a [NamedDataType] instead.

fn definition_named_data_type(type_map: &mut TypeCollection) -> NamedDataType

this is equivalent to [Type::definition] but returns a [NamedDataType] instead.

impl Serialize for DownloadDiskUsage

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Type for DownloadDiskUsage

fn inline(type_map: &mut TypeCollection, generics: Generics<'_>) -> DataType

Returns the definition of a type using the provided generics.

fn reference(type_map: &mut TypeCollection, generics: &[DataType]) -> Reference

Generates a datatype corresponding to a reference to this type, as determined by its category. Getting a reference to a type implies that it should belong in the type map (since it has to be referenced from somewhere), so the output of definition will be put into the type map.
