Extension trait for CID with additional encoding utilities

Required Methods

fn to_string_with_base(&self, base: MultibaseEncoding) -> String

Encode the CID to a string with the specified multibase encoding

fn to_v1(&self) -> Result<Cid>

Convert CIDv0 to CIDv1

CIDv0 is converted to CIDv1 with DAG-PB codec (0x70)

fn to_v0(&self) -> Result<Cid>

Try to convert CIDv1 to CIDv0

This only succeeds if:

• The hash algorithm is SHA2-256
• The codec is DAG-PB (0x70)

fn can_be_v0(&self) -> bool

Check if this CID can be represented as CIDv0

Returns true if the CID uses SHA2-256 and DAG-PB codec

fn is_v0(&self) -> bool

Check if this is a CIDv0

fn is_v1(&self) -> bool

Check if this is a CIDv1

fn codec_code(&self) -> u64

Get the codec code

fn hash_algorithm_name(&self) -> &'static str

Get the hash algorithm name

fn hash_algorithm_code(&self) -> u64

Get the hash algorithm code
