Struct MetadataRow 

pub struct MetadataRow {
    pub carrier: String,
    pub surface: String,
    pub path: String,
    pub language: Option<String>,
    pub value: String,
}

One extracted metadata value, addressed by carrier, surface, and path. The parent renders these to the tabular artifact and builds one hidden segment per row, so the output contract and the hidden marking stay in the crate rather than the worker.

Fields

carrier: String

The container the value came from, such as exif, png-itxt, jpeg-app1-xmp, webp-xmp, iptc-iim, or heic-uuid.

surface: String

The surface family, such as exif-imagedescription, xmp-dc-description, or iptc-2-120-caption.

path: String

The addressing detail, such as the exif tag number, the xmp property path, or the iptc dataset.

language: Option<String>

The language tag when the surface carries one, such as an iTXt language tag or an xmp xml:lang.

value: String

The extracted text.
