Struct WeakCid 

pub struct WeakCid(/* private fields */);

A CID that will be serialized as just bytes and will not be returned by crate::BlockLinks.

Implementations

impl WeakCid

pub fn new(cid: Cid<64>) -> WeakCid

pub fn cid(&self) -> Cid<64>

Methods from Deref<Target = Cid<64>>

pub fn version(&self) -> Version

Returns the cid version.

pub fn codec(&self) -> u64

Returns the cid codec.

pub fn hash(&self) -> &Multihash<S>

Returns the cid multihash.

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

where W: Write,

Writes the bytes to a byte stream, returns the number of bytes written.

pub fn encoded_len(&self) -> usize

Returns the length in bytes needed to encode this cid into bytes.

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, Error>

Convert CID into a multibase encoded string

Example

use cid::Cid;
use multibase::Base;
use multihash_codetable::{Code, MultihashDigest};

const RAW: u64 = 0x55;

let cid = Cid::new_v1(RAW, Code::Sha2_256.digest(b"foo"));
let encoded = cid.to_string_of_base(Base::Base64).unwrap();
assert_eq!(encoded, "mAVUSICwmtGto/8aP+ZtFPB0wQTQTQi1wZIO/oPmKXohiZueu");

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

Converts to this type from the input type.

impl From<Cid<64>> for WeakCid

fn from(value: Cid<64>) -> WeakCid

Converts to this type from the input type.

impl From<WeakCid> for Cid<64>

fn from(value: WeakCid) -> Cid<64>

Converts to this type from the input type.

impl Hash for WeakCid

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl JsonSchema for WeakCid

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl Ord for WeakCid

fn cmp(&self, other: &WeakCid) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

impl PartialEq for WeakCid

fn eq(&self, other: &WeakCid) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
