Struct AssetWitness 

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

A witness of an asset in an AssetVault.

It proves inclusion of a certain asset in the vault.

Implementations

impl AssetWitness

pub fn new(smt_proof: SmtProof) -> Result<AssetWitness, AssetError>

Creates a new AssetWitness from an SMT proof.

Errors

Returns an error if:

• any of the entries in the SMT leaf is not a valid asset.
• any of the entries’ vault keys does not match the expected vault key of the asset.

pub fn new_unchecked(smt_proof: SmtProof) -> AssetWitness

Creates a new AssetWitness from an SMT proof without checking that the proof contains valid assets.

Prefer AssetWitness::new whenever possible.

pub fn authenticates_asset_vault_key(&self, vault_key: AssetVaultKey) -> bool

Returns true if this AssetWitness authenticates the provided AssetVaultKey, i.e. if its leaf index matches, false otherwise.

pub fn find(&self, vault_key: AssetVaultKey) -> Option<Asset>

Searches for an Asset in the witness with the given vault_key.

pub fn assets(&self) -> impl Iterator<Item = Asset>

Returns an iterator over the Assets in this witness.

pub fn authenticated_nodes(&self) -> impl Iterator<Item = InnerNodeInfo>

Returns an iterator over every inner node of this witness’ merkle path.

Trait Implementations

impl Clone for AssetWitness

fn clone(&self) -> AssetWitness

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AssetWitness

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

Formats the value using the given formatter.

impl Deserializable for AssetWitness

fn read_from<R>(source: &mut R) -> Result<AssetWitness, DeserializationError>

where R: ByteReader,

Reads a sequence of bytes from the provided source, attempts to deserialize these bytes into Self, and returns the result.

fn read_from_bytes(bytes: &[u8]) -> Result<Self, DeserializationError>

Attempts to deserialize the provided bytes into Self and returns the result.

impl From<AssetWitness> for SmtProof

fn from(witness: AssetWitness) -> SmtProof

Converts to this type from the input type.

impl PartialEq for AssetWitness

fn eq(&self, other: &AssetWitness) -> 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 Serializable for AssetWitness

fn write_into<W>(&self, target: &mut W)

where W: ByteWriter,

Serializes self into bytes and writes these bytes into the target.

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

Serializes self into a vector of bytes.

fn get_size_hint(&self) -> usize

Returns an estimate of how many bytes are needed to represent self.
