Struct tiny_cid::Cid

pub struct Cid { /* fields omitted */ }

Representation of a CID.

Usually you would use Cid instead, unless you have a custom Multihash code table

Implementations

impl Cid

pub fn new_v0(hash: RawMultihash) -> Result<Self>

Create a new CIDv0.

pub fn new_v1(codec: u64, hash: RawMultihash) -> Self

Create a new CIDv1.

pub fn new(version: Version, codec: u64, hash: RawMultihash) -> Result<Self>

Create a new CID.

pub fn version(&self) -> Version

Returns the cid version.

pub fn codec(&self) -> u64

Returns the cid codec.

pub fn hash(&self) -> &RawMultihash

Returns the cid multihash.

pub fn read_bytes<R: Read>(r: R) -> Result<Self>

Reads the bytes from a byte stream.

pub fn write_bytes<W: Write>(&self, w: W) -> Result<()>

Writes the bytes to a byte stream.

pub fn to_bytes(&self) -> Vec<u8>

Returns the encoded bytes of the Cid.

pub fn to_string_of_base(&self, base: Base) -> Result<String>

Convert CID into a multibase encoded string

Example

use tiny_cid::{RAW, Cid};
use multibase::Base;
use tiny_multihash::{SHA2_256, Multihash, MultihashDigest};

let mh = Multihash::new(SHA2_256, b"foo").unwrap();
let cid = Cid::new_v1(RAW, mh.to_raw().unwrap());
let encoded = cid.to_string_of_base(Base::Base64).unwrap();
assert_eq!(encoded, "mAVUSICwmtGto/8aP+ZtFPB0wQTQTQi1wZIO/oPmKXohiZueu");
