[−][src]Trait punt::UsbContext

pub trait UsbContext: UsbContext {
    fn find_targets(&self) -> Result<Vec<Target<Self>>> { ... }
    fn pick_target(&self, serial: Option<&str>) -> Result<Target<Self>> { ... }
}

Base trait for a USB context.

Provided methods

`fn find_targets(&self) -> Result<Vec<Target<Self>>>`

Returns information about all connected targets in bootloader mode. USB devices not in bootloader mode cannot be detected, since their protocol for entering bootloader mode is not specified.

It returns Error::IoError on USB errors during device enumeration.

`fn pick_target(&self, serial: Option<&str>) -> Result<Target<Self>>`

Returns one target if either

A serial number is supplied which matches one of the connected targets' serial numbers or
Only one target is connected and either no serial number is supplied or the serial number matches.

It can return the following errors:

Error::TargetNotFound if no target is found based on the criteria above,
Error::TooManyMatches if more than one target is connected but no serial number is supplied, and
Error::IoError for any libusb errors occurring during USB transfers.

Just like with find_targets, only targets in bootloader mode are considered.
