Struct ads::symbol::Handle

source · [−]

pub struct Handle<'c> { /* private fields */ }

Expand description

A handle to a variable within the ADS device.

The handle is released automatically on drop.

Implementations

source

impl<'c> Handle<'c>

source

pub fn new(device: Device<'c>, symbol: &str) -> Result<Self>

Create a new handle to a single symbol.

source

pub fn read(&self, buf: &mut [u8 ]) -> Result<()>

Read data from the variable (returned data must match size of buffer).

source

pub fn write(&self, buf: &[u8 ]) -> Result<()>

Write data to the variable.
