Struct tokio_modbus::client::sync::Context

pub struct Context { /* private fields */ }

A synchronous Modbus client context.

Implementations

impl Context

pub const fn timeout(&self) -> Option<Duration>

Returns the current timeout.

pub fn set_timeout(&mut self, duration: impl Into<Option<Duration>>)

Sets a timeout duration for all subsequent operations.

The timeout is disabled by passing None.

pub fn reset_timeout(&mut self)

Disables the timeout for all subsequent operations.
