Struct Link 

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

A Link is a wrapper around a CID (Content Identifier) representing a reference to content stored via the iroh-blobs protocol.

Implementations

impl Link

pub fn new(codec: u64, hash: Hash) -> Self

Create a new Link from a codec and hash

pub fn codec(&self) -> u64

Get the codec of this link

pub fn hash(&self) -> Hash

Get the hash of this link

pub fn cid(&self) -> &Cid

Get the underlying CID

pub fn ticket( &self, source: PublicKey, format: Option<BlobFormat>, ) -> BlobTicket

Create a ticket for this link with an optional blob format

By default uses BlobFormat::Raw. For HashSeq collections, pass BlobFormat::HashSeq.

Trait Implementations

impl Clone for Link

fn clone(&self) -> Link

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Link

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Link

Links

A Link is a reference to a block of data stored by the iroh-blobs protocol. Links are implemented as Blake3 only multihashes wrapped in CIDs. CIDs encoding is used to communicate the expected encoding of the referenced content, while HashAndFormat is used for the retrieval of data over the iroh_blobs protocol. For our purposes, we keep the following assumptions:

• hashes are always blake3, and usually generated by iroh-blobs
• links may either be RAW or DAG-CBOR encoded depending on whether they point to:
  • public raw data (RAW)
  • private raw data (RAW)
  • private structured data (RAW, but underlying format is DAG-CBOR)
  • public structured data (DAG-CBOR)

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Link

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Link

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Cid<64>> for Link

fn from(val: Cid) -> Self

Converts to this type from the input type.

impl From<Link> for Cid

fn from(val: Link) -> Self

Converts to this type from the input type.

impl From<Link> for Hash

fn from(val: Link) -> Self

Converts to this type from the input type.

impl From<Link> for HashAndFormat

fn from(val: Link) -> Self

Converts to this type from the input type.

impl From<Link> for LinkedData

fn from(val: Link) -> Self

Converts to this type from the input type.

impl Hash for Link

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

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 Ord for Link

fn cmp(&self, other: &Link) -> 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.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Link

fn eq(&self, other: &Link) -> 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.

impl PartialOrd for Link

fn partial_cmp(&self, other: &Link) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Link

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
