Struct SendCommand 

pub struct SendCommand { /* private fields */ }

Send the subvolume(s) to stdout.

Generate a stream representation of one or more subvolumes that can be transmitted over the network or stored for later restoration. Streams are incremental and can be based on a parent subvolume to only send changes. The stream output is in btrfs send format and can be received with the receive command. Requires CAP_SYS_ADMIN.

With –offline, the kernel BTRFS_IOC_SEND ioctl is bypassed entirely and the stream is generated by reading the image directly via btrfs-fs. Useful for sending from images that aren’t mounted, FUSE mounts where the ioctl can’t complete, and unprivileged scenarios (no CAP_SYS_ADMIN required). Tier 1 of the send roadmap: full sends only — incremental, clone sources, NO_FILE_DATA, alternate protocol versions, and compressed-data passthrough are not yet supported in offline mode.

Trait Implementations

impl Args for SendCommand
