Struct Manifest 

pub struct Manifest {
    pub entries: BTreeMap<String, ManifestEntry>,
}

The full prior download state, keyed by clip id.

Backed by a BTreeMap so iteration order is stable, which keeps any plan derived from it deterministic.

Fields

entries: BTreeMap<String, ManifestEntry>

Records keyed by clip id.

Implementations

impl Manifest

pub fn new() -> Self

Create an empty manifest.

pub fn get(&self, clip_id: &str) -> Option<&ManifestEntry>

Return the entry for clip_id, if present.

pub fn insert( &mut self, clip_id: impl Into<String>, entry: ManifestEntry, ) -> Option<ManifestEntry>

Insert or replace the entry for clip_id, returning any prior value.

pub fn remove(&mut self, clip_id: &str) -> Option<ManifestEntry>

Remove and return the entry for clip_id, if present.

pub fn contains(&self, clip_id: &str) -> bool

Return true when an entry exists for clip_id.

pub fn iter(&self) -> Iter<'_, String, ManifestEntry>

Iterate entries in clip-id order.

pub fn len(&self) -> usize

Number of entries.

pub fn is_empty(&self) -> bool

True when there are no entries.

Trait Implementations

impl Clone for Manifest

fn clone(&self) -> Manifest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Manifest

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

Formats the value using the given formatter.

impl Default for Manifest

fn default() -> Manifest

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Manifest

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Manifest

impl PartialEq for Manifest

fn eq(&self, other: &Manifest) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Manifest

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
