Enum CopyMetadataDirective 

Source 
pub enum CopyMetadataDirective {
    Copy,
    Replace {
        content_type: Option<String>,
        user_metadata: BTreeMap<String, String>,
    },
}
Expand description

Metadata behavior for a server-side copy.

S3’s REPLACE directive replaces the complete metadata set. Keeping that choice explicit prevents changing one header from accidentally discarding all source user metadata.

Variants§

§

Copy

Copy the source object’s media type and user metadata unchanged.

§

Replace

Replace the complete metadata set with the supplied values.

Fields

§content_type: Option<String>

Replacement media type. When omitted, S3 applies its default.

§user_metadata: BTreeMap<String, String>

Complete replacement set of caller-defined metadata.
