Struct ChannelConfig 

pub struct ChannelConfig {
    pub channel_id: ChannelId,
    pub visibility: Visibility,
    pub publish_caps: Option<CapabilityFilter>,
    pub subscribe_caps: Option<CapabilityFilter>,
    pub require_token: bool,
    pub priority: u8,
    pub reliable: bool,
    pub max_rate_pps: Option<u32>,
}

Channel configuration with capability-based access control.

Authorization flow:

1. Node announces capabilities via CapabilityAd
2. If publish_caps is set, node’s CapabilitySet must match the filter
3. If require_token is true, node must also have a valid PermissionToken
4. On success, (origin_hash, channel_hash) is inserted into the AuthGuard

Fields

channel_id: ChannelId

Channel identity (name + hash).

visibility: Visibility

Visibility scope for subnet routing.

publish_caps: Option<CapabilityFilter>

Capability requirements for publishing. None = any node can publish.

subscribe_caps: Option<CapabilityFilter>

Capability requirements for subscribing. None = any node can subscribe.

require_token: bool

Whether a valid PermissionToken is required (in addition to capabilities).

priority: u8

Default priority level for this channel’s packets (0 = lowest).

reliable: bool

Default reliability mode for streams on this channel.

max_rate_pps: Option<u32>

Optional rate limit in packets per second.

Implementations

impl ChannelConfig
