Information on the voting tracks.

Required Associated Types

type Id: Copy + Parameter + Ord + PartialOrd + Send + Sync + 'static + MaxEncodedLen

The identifier for a track.

type RuntimeOrigin

The origin type from which a track is implied.

Required Methods

fn tracks() -> impl Iterator<Item = Cow<'static, Track<Self::Id, Balance, Moment, N>>>

Return the sorted iterable list of known tracks and their information.

The iterator MUST be sorted by Id. Consumers of this trait are advised to assert Self::check_integrity prior to any use.

fn track_for(origin: &Self::RuntimeOrigin) -> Result<Self::Id, ()>

Determine the voting track for the given origin.

Provided Methods

fn track_ids() -> impl Iterator<Item = Self::Id>

Return the list of identifiers of the known tracks.

fn info(id: Self::Id) -> Option<Cow<'static, TrackInfo<Balance, Moment, N>>>

Return the track info for track id, by default this just looks it up in Self::tracks().

fn check_integrity() -> Result<(), &'static str>

Check assumptions about the static data that this trait provides.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
