Struct ExtDataControlOfferV1

pub struct ExtDataControlOfferV1 { /* private fields */ }

offer to transfer data

A ext_data_control_offer represents a piece of data offered for transfer by another client (the source client). The offer describes the different MIME types that the data can be converted to and provides the mechanism for transferring the data directly from the source client.

See also the Event enum for this interface.

Implementations

impl ExtDataControlOfferV1

pub fn receive(&self, mime_type: String, fd: BorrowedFd<'_>)

request that the data is transferred

To transfer the offered data, the client issues this request and indicates the MIME type it wants to receive. The transfer happens through the passed file descriptor (typically created with the pipe system call). The source client writes the data in the MIME type representation requested and then closes the file descriptor.

The receiving client reads from the read end of the pipe until EOF and then closes its end, at which point the transfer is complete.

This request may happen multiple times for different MIME types.

pub fn destroy(&self)

destroy this offer

Destroys the data offer object.

impl PartialEq<Weak<ExtDataControlOfferV1>> for ExtDataControlOfferV1

fn eq(&self, other: &Weak<ExtDataControlOfferV1>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
