Struct ReplacementPolicy 

pub(super) struct ReplacementPolicy {
    source: File,
    metadata: Metadata,
    attributes: Vec<(&'static str, Option<Vec<u8>>)>,
}

A retained regular destination and its opaque native access policy.

Fields

source: File

Keep the snapshotted inode alive through publication.

metadata: Metadata

Ownership, mode and filesystem identity associated with that inode.

attributes: Vec<(&'static str, Option<Vec<u8>>)>

Supported native attributes, including verified absence.

Implementations

impl ReplacementPolicy

pub(super) fn capture(path: &Path, expected: &Metadata) -> Result<Self>

Snapshot through a no-follow descriptor, without requiring data-read access on write-only files.

pub(super) fn permissions(&self) -> Permissions

Create a probe with the destination’s ordinary mode, filtered by current umask.

pub(super) fn matches(&self, file: &File) -> Result<bool>

Prove the complete observable policy already matches, without any setters.

pub(super) fn verify_destination(&self, path: &Path) -> Result<()>

Refuse replacement after the admitted destination or its captured policy changes.

pub(super) fn apply(&self, file: &File) -> Result<()>

Apply only changed attributes, then prove the complete policy before naming.

pub(super) fn anonymous_stage( &self, builder: &Builder<'_, '_>, guard: &ProjectStateGuard, bytes: &[u8], ) -> Result<NamedTempFile>

Prepare the complete replacement while unnamed; only then expose a staging name.
