Struct RsyncCapabilities 

pub struct RsyncCapabilities {
    pub info_flags: bool,
    pub stats_regular_file_breakdown: bool,
    pub compress_choice: bool,
    pub append_verify: bool,
    pub no_motd: bool,
}

What a given rsync binary accepts. Every transfer builder asks this struct for its argv fragments instead of hard-coding rsync 3.x flags.

Fields

info_flags: bool

--info=progress2 / --info=stats2 / --info=name2 (rsync >= 3.1).

stats_regular_file_breakdown: bool

--stats prints Number of files: N (reg: R, dir: D) (rsync >= 3.1), which the zero-build-output detector uses as its completeness cross-check. Without it the detector fails open.

compress_choice: bool

--compress-choice=zstd (rsync >= 3.2). Without it -z means zlib and --compress-level is capped at 9.

append_verify: bool

--append-verify (rsync >= 3.0). Without it resumable uploads rely on --partial plus the delta algorithm alone.

no_motd: bool

--no-motd (rsync >= 3.0, openrsync).

Implementations

impl RsyncCapabilities

pub const MODERN: Self

Everything rch’s preferred argv needs (rsync >= 3.2).

pub const LEGACY: Self

The openrsync / rsync 2.6.9 compatibility set.

pub const fn is_compatibility_mode(&self) -> bool

Whether the compatibility argv (rather than the preferred one) is in use.

pub const fn progress_args(&self) -> &'static [&'static str]

Progress reporting that refreshes often enough to feed the silence stall detector. --info=progress2 prints one cumulative line refreshed with bare \r; legacy --progress prints a per-file line in the same <bytes> <pct>% <rate> <eta> (xfer#N, to-check=A/B) shape.

pub const fn stats_args(&self) -> &'static [&'static str]

Transfer statistics block (Number of files transferred:, sent N bytes). Both spellings print the lines parse_rsync_bytes / parse_rsync_files read.

pub const fn name_listing_args(&self) -> &'static [&'static str]

Make rsync itemize EVERY matched regular file, including up-to-date ones (.f lines), when combined with --out-format='%i %n'. --info=name2 is the modern spelling; -vv is the pre-3.1 one and is what openrsync honours (verified: -v alone lists only transferred files, -vv also lists the .f matches).

pub fn compression_args(&self, level: u32) -> Vec<String>

Compression flags for a requested zstd level (0 disables).

Modern rsync gets --compress-choice=zstd --compress-level=N. A legacy binary compresses with zlib via the -z every builder already passes, so only --compress-level is emitted, clamped to zlib’s maximum of 9.

pub const fn resume_args(&self) -> &'static [&'static str]

Resumable-upload flags for an immutable file: --partial always, plus --append-verify where supported so a retry extends the remote partial in place instead of re-deltaing it.

pub const fn no_motd_args(&self) -> &'static [&'static str]

--no-motd where supported (suppresses daemon-mode banners that would pollute parsed stdout); nothing otherwise.
