Struct BridgeBuilder 

pub struct BridgeBuilder<S, TX, D = NoDelay> { /* private fields */ }

Builder for Bridge. Obtain via Bridge::builder().

Uses a typestate pattern: S and TX start as () and are replaced when .rtu() is called, preventing .build() before the serial port is supplied. D starts as NoDelay and can be upgraded with .delay().

Implementations

impl BridgeBuilder<(), (), NoDelay>

pub fn new() -> Self

Creates a new BridgeBuilder with no serial port configured.

Prefer Bridge::builder() over calling this directly.

impl<D> BridgeBuilder<(), (), D>

pub fn rtu<S, TX>(self, serial: S, tx_en: TX) -> BridgeBuilder<S, TX, D>

Supplies the serial port and RS-485 TX-enable pin.

Examples

let bridge = Bridge::builder()
    .rtu(uart, tx_en_pin)
    .build();

pub fn rtu_no_pin<S>(self, serial: S) -> BridgeBuilder<S, NoPin, D>

Supplies the serial port without a TX-enable pin.

Use this when the RS-485 transceiver handles direction control automatically.

Examples

let bridge = Bridge::builder()
    .rtu_no_pin(uart)
    .build();

impl<S, TX, D> BridgeBuilder<S, TX, D>

pub fn rtu_timeout(self, ms: u32) -> Self

Sets the RTU I/O timeout in milliseconds.

Applied while waiting for the RTU device response in each cycle. Requires a delay provider — call .delay() as well.

pub fn tcp_timeout(self, ms: u32) -> Self

Sets the TCP I/O timeout in milliseconds.

Applied while waiting for an incoming TCP request in each cycle. Requires a delay provider — call .delay() as well.

pub fn build(self) -> Bridge<S, TX, D>

Builds and returns the configured Bridge.

Examples

let mut bridge = Bridge::builder()
    .rtu(uart, tx_en)
    .build();

impl<S, TX> BridgeBuilder<S, TX, NoDelay>

pub fn delay<D2>(self, delay: D2) -> BridgeBuilder<S, TX, D2>

Supplies a delay provider and upgrades D from NoDelay.

Must be called before .build() when using .rtu_timeout() or .tcp_timeout().

Examples

let bridge = Bridge::builder()
    .rtu(uart, pin)
    .rtu_timeout(500)
    .delay(my_timer)
    .build();

Trait Implementations

impl Default for BridgeBuilder<(), (), NoDelay>

fn default() -> Self

Returns the “default value” for a type.
