Struct BlobId

pub struct BlobId {
    pub hash: CryptoHash,
    pub blob_type: BlobType,
}

A content-addressed blob ID i.e. the hash of the BlobContent.

Fields

hash: CryptoHash

The hash of the blob.

blob_type: BlobType

The type of the blob.

Implementations

impl BlobId

pub fn from_content(content: &BlobContent) -> Self
