Enum Reference 

pub enum Reference {
    Plain([u8; 32]),
    Encrypted([u8; 64]),
}

Swarm content reference. 32 bytes for a plain CAC reference, 64 bytes for an encrypted reference (CAC address || encryption key).

Variants

Plain([u8; 32])

Plain 32-byte reference (BMT root over the chunk).

Encrypted([u8; 64])

Encrypted 64-byte reference (32-byte CAC addr || 32-byte key).

Implementations

impl Reference

pub const ALLOWED_LENGTHS: &'static [usize]

All accepted lengths.

pub fn new(b: &[u8]) -> Result<Self, Error>

Construct from raw bytes. Length must be 32 or 64.

pub fn from_hex(s: &str) -> Result<Self, Error>

Parse from hex (with or without 0x prefix).

pub fn as_bytes(&self) -> &[u8]

Borrow the raw bytes (32 or 64).

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

Owned copy of the raw bytes (32 or 64).

pub fn to_hex(&self) -> String

Lowercase hex, no 0x prefix.

pub fn is_encrypted(&self) -> bool

True for the 64-byte encrypted variant.

pub fn len(&self) -> usize

Length in bytes (32 or 64).

pub fn is_empty(&self) -> bool

Whether this reference holds zero bytes — never true for a constructed Reference but useful in default-value paths.

Trait Implementations

impl Clone for Reference

fn clone(&self) -> Reference

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Reference

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Reference

fn deserialize<D: Deserializer<'de>>(d: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for Reference

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

Formats the value using the given formatter.

impl From<Reference> for ResourceLocator

fn from(r: Reference) -> Self

Converts to this type from the input type.

impl FromStr for Reference

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Reference

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 LowerHex for Reference

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

Formats the value using the given formatter.

impl PartialEq for Reference

fn eq(&self, other: &Reference) -> 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 Serialize for Reference

fn serialize<S: Serializer>(&self, s: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl Eq for Reference

impl StructuralPartialEq for Reference
