Struct wishbone_bridge::Bridge

pub struct Bridge { /* fields omitted */ }

Bridges represent the actual connection to the device. You must create a Bridge by constructing a configuration from the relevant configuration type, and then calling create().

For example, to create a USB bridge, use the UsbBridge object:

use wishbone_bridge::UsbBridge;
let mut bridge_config = UsbBridge::new();
let bridge = bridge_config.pid(0x1234).create().unwrap();

Implementations

impl Bridge

pub fn connect(&self) -> Result<(), BridgeError>

Ensure the bridge is connected. Many bridges support performing connection in the background, so calling connect() ensures that the bridge has been established.

pub fn peek(&self, addr: u32) -> Result<u32, BridgeError>

Read a single 32-bit value from the target device.

use wishbone_bridge::UsbBridge;
let mut bridge_config = UsbBridge::new();
let bridge = bridge_config.pid(0x5bf0).create().unwrap();
println!("The value at address 0 is: {:08x}", bridge.peek(0).unwrap());

pub fn poke(&self, addr: u32, value: u32) -> Result<(), BridgeError>

Write a single 32-bit value into the specified address.

use wishbone_bridge::UsbBridge;
let mut bridge_config = UsbBridge::new();
let bridge = bridge_config.pid(0x5bf0).create().unwrap();
// Poke 0x12345678 into the target device at address 0
bridge.poke(0, 0x12345678).unwrap();

Trait Implementations

impl Clone for Bridge

fn clone(&self) -> Bridge

Returns a copy of the value.

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

Performs copy-assignment from source.
