Struct Handle

pub struct Handle<T: UsbContext> { /* private fields */ }

A handle to a calculator.

Implementations

impl<T: UsbContext> Handle<T>

pub fn new(device: DeviceHandle<T>) -> Result<Self>

Create a new handle to a USB device.

pub fn is_cx_ii(&self) -> Result<bool>

Whether this device is a CX II, CAS or non-CAS.

pub fn info(&self) -> Result<Info>

pub fn screenshot(&self) -> Result<Image>

Take a screenshot.

pub fn move_file(&self, src: &str, dest: &str) -> Result<()>

Move/rename a file.

pub fn file_attr(&self, src: &str) -> Result<DirItem>

Get the attributes of a file or directory.

pub fn copy_file(&self, src: &str, dest: &str) -> Result<()>

Copy a file.

pub fn delete_file(&self, path: &str) -> Result<()>

Delete a file.

pub fn read_file( &self, path: &str, buf: &mut [u8], progress: &mut dyn FnMut(usize), ) -> Result<usize>

Read a file. Returns the number of bytes read. You must pass a buffer large enough to read the entire file (or smaller if that’s all you care about).

pub fn write_file( &self, path: &str, buf: &[u8], progress: &mut dyn FnMut(usize), ) -> Result<()>

Write a file.

pub fn send_os(&self, buf: &[u8], progress: &mut dyn FnMut(usize)) -> Result<()>

Send an OS update.

pub fn create_dir(&self, path: &str) -> Result<()>

Create a directory.

pub fn delete_dir(&self, path: &str) -> Result<()>

Delete a directory.

pub fn list_dir(&self, path: &str) -> Result<DirList>

Get the contents of a directory.

Trait Implementations

impl<T: UsbContext> Drop for Handle<T>

fn drop(&mut self)

Executes the destructor for this type.

impl<T: UsbContext> TryFrom<DeviceHandle<T>> for Handle<T>

type Error = Error

The type returned in the event of a conversion error.

fn try_from(device: DeviceHandle<T>) -> Result<Self>

Performs the conversion.
