ShardView

Struct ShardView 

Source
pub struct ShardView {
    pub channels: BTreeMap<ChannelId, Channel>,
    pub users: BTreeMap<SessionId, User>,
}
Expand description

Everything one shard renders, each fact held once.

Fields§

§channels: BTreeMap<ChannelId, Channel>§users: BTreeMap<SessionId, User>

Implementations§

Source§

impl ShardView

Source

pub fn empty() -> ShardView

The view a connection holds before it has been told anything.

Source

pub fn restrict(&self, see: ScopeSet) -> ShardView

The part of this view visible to see.

Used only on the slow path (guide 9.4), where a connection has to learn a whole new subtree. The fast path never materializes a per-connection view at all - that is the point of the design.

Source

pub fn compose(&self, overlay: &Overlay) -> ShardView

This view with overlay layered on top.

There is nothing to reconcile: shared and private are disjoint by construction (guide 3.4), so this is a union, and an element appearing in both would be a build error caught long before here.
