Struct ObjectMeta

Source

pub struct ObjectMeta {

    pub last_modified: DateTime<Utc>,
    pub size: u64,
    pub e_tag: Option<String>,
    pub version: Option<String>,

Expand description

The metadata that describes an object.

Fields§

§location: Path

The full path to the object

§last_modified: DateTime<Utc>

The last modified time

§size: u64

The size in bytes of the object.

Note this is not usize as object_store supports 32-bit architectures such as WASM

§e_tag: Option<String>

The unique identifier for the object

https://datatracker.ietf.org/doc/html/rfc9110#name-etag

§version: Option<String>

A version indicator for this object
