BusRoute

Enum BusRoute 

Source
pub enum BusRoute {
    Direct(Speed),
    Translated(SplitInfo),
}
Expand description

How a device’s traffic reaches it on the bus.

Unifies the device speed with the optional split-transaction (or legacy PRE prefix) routing. Illegal combinations (a high-speed device reached through a TT or PRE) are unrepresentable: BusRoute::Translated wraps a SplitInfo whose SplitSpeed only admits low or full speed.

Variants§

§

Direct(Speed)

No bus-level translation. The device runs at its native speed and is addressed directly. Covers root-port devices and any device whose traffic is not re-clocked by an intermediate hub (high-speed device behind a high-speed hub, full-speed device behind a full-speed hub).

§

Translated(SplitInfo)

The device is reached through a transaction translator on a high-speed controller (USB 2.0 §11.14), or via a legacy PRE prefix on a full-speed controller (USB 1.1 §11.8.6). The device’s speed is recorded inside the SplitInfo.

Implementations§

Source§

impl BusRoute

Source

pub const fn device_speed(self) -> Speed

Speed at which the target device operates.

Source

pub const fn split(self) -> Option<SplitInfo>

Returns the SplitInfo describing TT/PRE routing, or None when the device is reached directly.
