Struct FunctionalDescriptor

pub struct FunctionalDescriptor {
    pub can_download: bool,
    pub can_upload: bool,
    pub manifestation_tolerant: bool,
    pub will_detach: bool,
    pub detach_timeout: u16,

}

Functional descriptor.

Fields

can_download: bool

bitCanDnload.

Bit 0: download capable.

can_upload: bool

bitCanUpload.

Bit 1: upload capable.

manifestation_tolerant: bool

bitManifestationTolerant.

Bit 2: device is able to communicate via USB after Manifestation phase.

will_detach: bool

bitWillDetach.

Bit 3: device will perform a bus detach-attach sequence when it receives a DFU_DETACH request. The host must not issue a USB Reset.

detach_timeout: u16

wDetachTimeOut.

Time, in milliseconds, that the device will wait after receipt of the DFU_DETACH request. If this time elapses without a USB reset, then the device will terminate the Reconfiguration phase and revert back to normal operation. This represents the maximum time that the device can wait (depending on its timers, etc.). The host may specify a shorter timeout in the DFU_DETACH request.

transfer_size: u16

wTransferSize.

Maximum number of bytes that the device can accept per control-write transaction.

dfu_version: (u8, u8)

bcdDFUVersion.

Numeric expression identifying the version of the DFU Specification release.
