[−][src]Struct tiny_cid::Cid
Representation of a CID.
Usually you would use Cid
instead, unless you have a custom Multihash code table
Implementations
impl Cid
[src]
pub fn new_v0(hash: RawMultihash) -> Result<Self>
[src]
Create a new CIDv0.
pub fn new_v1(codec: u64, hash: RawMultihash) -> Self
[src]
Create a new CIDv1.
pub fn new(version: Version, codec: u64, hash: RawMultihash) -> Result<Self>
[src]
Create a new CID.
pub fn version(&self) -> Version
[src]
Returns the cid version.
pub fn codec(&self) -> u64
[src]
Returns the cid codec.
pub fn hash(&self) -> &RawMultihash
[src]
Returns the cid multihash.
pub fn read_bytes<R: Read>(r: R) -> Result<Self>
[src]
Reads the bytes from a byte stream.
pub fn write_bytes<W: Write>(&self, w: W) -> Result<()>
[src]
Writes the bytes to a byte stream.
pub fn to_bytes(&self) -> Vec<u8>
[src]
Returns the encoded bytes of the Cid
.
pub fn to_string_of_base(&self, base: Base) -> Result<String>
[src]
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");
