Struct ClientBuilder 

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

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

Uses the same typestate pattern as BridgeBuilder. S and TX start as () until .rtu() is called. D starts as NoDelay and can be upgraded with .delay().

Implementations

impl ClientBuilder<(), (), NoDelay>

pub fn new() -> Self

Creates a new ClientBuilder with no serial port configured.

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

impl<D> ClientBuilder<(), (), D>

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

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

Examples

let client = Client::builder()
    .rtu(uart, tx_en_pin)
    .build();

pub fn rtu_no_pin<S>(self, serial: S) -> ClientBuilder<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 client = Client::builder()
    .rtu_no_pin(uart)
    .build();

impl<S, TX, D> ClientBuilder<S, TX, D>

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

Sets the RTU I/O timeout in milliseconds.

Applied while waiting for an incoming RTU request from the serial master. 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 the upstream TCP server response. Requires a delay provider — call .delay() as well.

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

Builds and returns the configured Client.

Examples

let mut client = Client::builder()
    .rtu(uart, tx_en)
    .build();

impl<S, TX> ClientBuilder<S, TX, NoDelay>

pub fn delay<D2>(self, delay: D2) -> ClientBuilder<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 client = Client::builder()
    .rtu(uart, pin)
    .rtu_timeout(500)
    .delay(my_timer)
    .build();

Trait Implementations

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

fn default() -> Self

Returns the “default value” for a type.
