Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

size: u64

Size of the object in bytes.

Refers to the Content-Length HTTP header for HeadObject.

last_modified: OffsetDateTime

The time this object was last modified.

etag: ETag

Entity tag of this object.

storage_class: Option<String>

Storage class for this object.

The value is optional because HeadObject does not return the storage class in its response for objects in the S3 Standard storage class. See examples in the Amazon S3 API Reference.

restore_status: Option<RestoreStatus>

Objects in flexible retrieval storage classes (such as GLACIER and DEEP_ARCHIVE) are only accessible after restoration

checksum: Checksum

Checksum of the object.

HeadObject must explicitly request for this field to be included, otherwise the values will be empty.

sse_type: Option<String>

Server-side encryption type that was used to store the object.

sse_kms_key_id: Option<String>

Server-side encryption KMS key ID that was used to store the object.

Trait Implementations

impl Debug for HeadObjectResult

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

Formats the value using the given formatter.
