Struct Metadata

pub struct Metadata { /* private fields */ }

The metadata for all files we’re tracking.

The implementations of agde need to provide methods to create and save this.

You can call Clone::clone_from for an optimized cloning method.

Implementations

impl Metadata

pub fn new(map: HashMap<String, ResourceMeta>) -> Self

Create a new metadata map.

pub fn iter(&self) -> impl Iterator<Item = (&str, ResourceMeta)>

Get an iterator over all the resources and their respective metadata.

pub fn get(&self, resource: &str) -> Option<ResourceMeta>

Get the metadata for resource.

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

If the metadata contains resource.

pub fn remove(&mut self, resource: &str)

Remove the metadata for resource.

pub fn insert(&mut self, resource: String, meta: ResourceMeta)

Insert the meta for resource.

pub fn changes( &self, target: &Self, ignore_mtime_of_last_event: bool, ) -> Vec<MetadataChange>

Calculate the changes to get the metadata from self to target.

ignore_mtime_of_last_event is used when diffing locally, as we don’t care about the unrelated mtime_of_last_event in the current storage.

pub fn apply_changes(&mut self, changes: &[MetadataChange], target: &Self)

Apply the changes gathered from Self::changes to self, while fetching data from target.

This means you can apply the changes between two metadata sets on a third set.

Also see Self::apply_current_mtime_changes

pub fn apply_current_mtime_changes(&mut self, changes: &[MetadataChange])

Same as Self::apply_changes but also apply the ResourceMeta::mtime_in_current to get self to target.

This is here to update the mtime of resources which did not get their mtime updated due to the diff being empty.

Trait Implementations

impl Clone for Metadata

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Metadata

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Metadata

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Metadata

fn eq(&self, other: &Metadata) -> 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 Metadata

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Metadata

impl StructuralPartialEq for Metadata
