A chain of DIDs.

Required Methods

fn len(&self) -> usize

Returns the length of the DID chain.

fn level(&self, did: &str) -> Option<usize>

Returns the level of the given DID in the chain.

fn root(&self) -> &str

Gets the root DID.

fn leaf(&self) -> &str

Gets the leaf node DID.

fn upstream(&self, did: &str) -> Option<&String>

Gets the next upstream DID.

fn downstream(&self, did: &str) -> Option<&String>

Gets the next downstream DID.

fn data(&self, did: &str) -> Option<&(Document, DocumentMetadata)>

Gets data for the given DID.

fn verify_proofs(&self) -> Result<(), ChainError>

Verify all of the proofs in the chain.

fn level_vec(&self) -> &Vec<String>

Returns a vector of DID strings ordered by the level in the chain, starting at the root (level 0).

Provided Methods

fn to_vec(&self) -> Vec<(Document, DocumentMetadata)>

Returns a vector of Documents and Document Metadata for each DID ordered by the level in the chain, starting at the root (level 0).

fn is_empty(&self) -> bool

Returns whether the Chain is empty
