Struct Object

#[non_exhaustive]
pub struct Object {
    pub key: Option<String>,
    pub last_modified: Option<DateTime>,
    pub e_tag: Option<String>,
    pub checksum_algorithm: Option<Vec<ChecksumAlgorithm>>,
    pub size: Option<i64>,
    pub storage_class: Option<ObjectStorageClass>,
    pub owner: Option<Owner>,
    pub restore_status: Option<RestoreStatus>,
}

An object consists of data and its descriptive metadata.

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.

key: Option<String>

The name that you assign to an object. You use the object key to retrieve the object.

last_modified: Option<DateTime>

Creation date of the object.

e_tag: Option<String>

The entity tag is a hash of the object. The ETag reflects changes only to the contents of an object, not its metadata. The ETag may or may not be an MD5 digest of the object data. Whether or not it is depends on how the object was created and how it is encrypted as described below:

• Objects created by the PUT Object, POST Object, or Copy operation, or through the Amazon Web Services Management Console, and are encrypted by SSE-S3 or plaintext, have ETags that are an MD5 digest of their object data.

• Objects created by the PUT Object, POST Object, or Copy operation, or through the Amazon Web Services Management Console, and are encrypted by SSE-C or SSE-KMS, have ETags that are not an MD5 digest of their object data.

• If an object is created by either the Multipart Upload or Part Copy operation, the ETag is not an MD5 digest, regardless of the method of encryption. If an object is larger than 16 MB, the Amazon Web Services Management Console will upload or copy that object as a Multipart Upload, and therefore the ETag will not be an MD5 digest.

Directory buckets - MD5 is not supported by directory buckets.

checksum_algorithm: Option<Vec<ChecksumAlgorithm>>

The algorithm that was used to create a checksum of the object.

size: Option<i64>

Size in bytes of the object

storage_class: Option<ObjectStorageClass>

The class of storage used to store the object.

Directory buckets - Only the S3 Express One Zone storage class is supported by directory buckets to store objects.

owner: Option<Owner>

The owner of the object

Directory buckets - The bucket owner is returned as the object owner.

restore_status: Option<RestoreStatus>

Specifies the restoration status of an object. Objects in certain storage classes must be restored before they can be retrieved. For more information about these storage classes and how to work with archived objects, see Working with archived objects in the Amazon S3 User Guide.

This functionality is not supported for directory buckets. Only the S3 Express One Zone storage class is supported by directory buckets to store objects.

Implementations

impl Object

pub fn key(&self) -> Option<&str>

The name that you assign to an object. You use the object key to retrieve the object.

pub fn last_modified(&self) -> Option<&DateTime>

Creation date of the object.

pub fn e_tag(&self) -> Option<&str>

The entity tag is a hash of the object. The ETag reflects changes only to the contents of an object, not its metadata. The ETag may or may not be an MD5 digest of the object data. Whether or not it is depends on how the object was created and how it is encrypted as described below:

• If an object is created by either the Multipart Upload or Part Copy operation, the ETag is not an MD5 digest, regardless of the method of encryption. If an object is larger than 16 MB, the Amazon Web Services Management Console will upload or copy that object as a Multipart Upload, and therefore the ETag will not be an MD5 digest.

Directory buckets - MD5 is not supported by directory buckets.

pub fn checksum_algorithm(&self) -> &[ChecksumAlgorithm]

The algorithm that was used to create a checksum of the object.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .checksum_algorithm.is_none().

pub fn size(&self) -> Option<i64>

Size in bytes of the object

pub fn storage_class(&self) -> Option<&ObjectStorageClass>

The class of storage used to store the object.

Directory buckets - Only the S3 Express One Zone storage class is supported by directory buckets to store objects.

pub fn owner(&self) -> Option<&Owner>

The owner of the object

Directory buckets - The bucket owner is returned as the object owner.

pub fn restore_status(&self) -> Option<&RestoreStatus>

Specifies the restoration status of an object. Objects in certain storage classes must be restored before they can be retrieved. For more information about these storage classes and how to work with archived objects, see Working with archived objects in the Amazon S3 User Guide.

This functionality is not supported for directory buckets. Only the S3 Express One Zone storage class is supported by directory buckets to store objects.

impl Object

pub fn builder() -> ObjectBuilder

Creates a new builder-style object to manufacture Object.

Trait Implementations

impl Clone for Object

fn clone(&self) -> Object

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Object

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

Formats the value using the given formatter.

impl PartialEq for Object

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