    pub content_length: Option<i64>,
    pub content_type: Option<String>,
    pub last_modified: Option<i64>,
    pub etag: Option<String>,

    pub metadata: HashMap<String, String>,
}

All properties returned by HeadObject for a single S3 object.

User-defined metadata (x-amz-meta-*) is surfaced in metadata. All fields are optional — not every object or provider returns every header.

Fields

content_length: Option<i64>

Object size in bytes.

content_type: Option<String>

MIME type, e.g. "application/octet-stream".

last_modified: Option<i64>

RFC 2822 last-modified timestamp as a Unix epoch (seconds).

etag: Option<String>

HTTP ETag string (including surrounding quotes from S3).

version_id: Option<String>

Version ID if the bucket has versioning enabled.

storage_class: Option<String>

S3 storage class, e.g. "STANDARD", "GLACIER".

server_side_encryption: Option<String>

Server-side encryption algorithm, e.g. "aws:kms" or "AES256".

sse_kms_key_id: Option<String>

KMS key ID when SSE-KMS is active.

content_encoding: Option<String>

Content-Encoding header value, e.g. "gzip".

content_disposition: Option<String>

Content-Disposition header value.

cache_control: Option<String>

Cache-Control header value.

expires: Option<i64>

Expires header as Unix epoch (seconds), if present.

metadata: HashMap<String, String>

User-defined metadata (keys stripped of the x-amz-meta- prefix).

Trait Implementations

impl Clone for ObjectHead

fn clone(&self) -> ObjectHead

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ObjectHead

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ObjectHead

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ObjectHead

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

impl Serialize for ObjectHead

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
