Struct BlockMetadata 

pub struct BlockMetadata {
    pub cid: SerializableCid,
    pub size: BlockSize,
    pub links: usize,
}

Metadata about a block for indexing and queries.

This lightweight structure contains summary information about a block without holding the actual data. Useful for block indices and caches.

Fields

cid: SerializableCid

Content identifier of the block

size: BlockSize

Size of the block data in bytes

links: usize

Number of CID links to other blocks (for DAG nodes)

Implementations

impl BlockMetadata

pub fn new(cid: Cid, size: BlockSize) -> Self

Creates new block metadata with the given CID and size.

The number of links is initialized to 0.

pub fn with_links(self, links: usize) -> Self

Sets the number of CID links in this block.

This is useful for DAG nodes that reference other blocks.
