Struct MetaInfo 

pub struct MetaInfo {
    pub content_type: Option<ContentType>,
    pub freshness_period: Option<FreshnessPeriod>,
    pub final_block_id: Option<FinalBlockId>,
}

Metadata describing a Data packet’s content: its ContentType, FreshnessPeriod, and FinalBlockId, all optional.

Fields

What kind of content this is.

freshness_period: Option<FreshnessPeriod>

How long the content stays fresh for.

final_block_id: Option<FinalBlockId>

The final segment’s name component, for segmented content.
