Struct ObjectMetadata 

pub struct ObjectMetadata {
    pub etag: Option<String>,
    pub version: Option<String>,
    pub size_bytes: u64,
    pub last_modified_ms: Option<u64>,
}

Metadata returned by a successful head, full-object get, or put call.

Fields

etag: Option<String>

Opaque compare token for one object version.

This is suitable for immediate compare-and-swap on the same object key. It is not canonical content identity and callers must not derive provider-specific meaning from it.

version: Option<String>

Provider version identifier when available.

size_bytes: u64

Complete object length in bytes at the observed version.

last_modified_ms: Option<u64>

Provider last-modified time in unix milliseconds, when available.

Advisory: garbage collection uses it for grace/reap age checks and treats an absent value as “young” (retain). Never a validity input.
