Enum CopyAction 

enum CopyAction {
    Copy,
    Overwrite,
    Preserve,
    TieBreakByBytes,
    Conflict,
}

Per-file decision inside move_zone’s retry-aware loop. See the doc comment in move_zone for which round each variant addresses.

Variants

Copy

Destination missing the file (R5 partial-copy fill).

Overwrite

Source strictly newer than destination (R6 newer-source promotion).

Preserve

Destination strictly newer than source (R4 user-continuation on destination clone) — or equal-modts + equal bytes.

TieBreakByBytes

Equal modts; need to read both sides and compare bytes.

Conflict

Equal modts but bytes differ — neither side is canonical (R7 same-ms conflict). Preserve destination, leave source.

Trait Implementations

impl Clone for CopyAction

fn clone(&self) -> CopyAction

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CopyAction

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for CopyAction

fn eq(&self, other: &CopyAction) -> 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.
