Expand description

Metadata carries all object metadata.

Implementations

source

impl ObjectMetadata

source

pub fn mode(&self) -> ObjectMode

Object mode represent this object’ mode.

source

pub fn content_length(&self) -> u64

Content length of this object

Content-Length is defined by RFC 7230 Refer to MDN Content-Length for more information.

source

pub fn content_md5(&self) -> Option<&str>

Content MD5 of this object.

Content Length is defined by RFC 2616. And removed by RFC 7231.

OpenDAL will try its best to set this value, but not guarantee this value is the md5 of content.

source

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

Last modified of this object.

Last-Modified is defined by RFC 7232 Refer to MDN Last-Modified for more information.

OpenDAL parse the raw value into OffsetDateTime for convenient.

source

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

ETag of this object.

ETag is defined by RFC 7232 Refer to MDN ETag for more information.

OpenDAL will return this value AS-IS like the following:

"33a64df551425fcc55e4d42a148795d9f25f89d4"
W/"0815"

" is part of etag.
