Struct glycos::graph::cryptograph::Vertex

pub struct Vertex {
    owner: PublicKey,
    owner_recogniser: Recogniser,
    owner_cek: Option<Vec<u8>>,
    recogniser: Recogniser,
    acl: VertexControlList,
    acl_ephemeral: PublicKey,
    value: Option<Vec<u8>>,
    pub clock: u32,
    signature: SchnorrSignature,
}

Represents a sealed vertex.

It can be opened to a primitive Vertex by calling decrypt.

Implementations

impl Vertex

pub fn verify_signature(&self) -> bool

Verifies that the signature of this Vertex is correct.

Returns true when the signature is valid, false otherwise. Call this method after receiving a vertex, and do not consume it if it’s invalid.

pub fn check_acl(&self, sk: &PrivateKey) -> Result<Option<PrivateKey>>

Checks sk’s eligibility for appending to this vertex.

When eligible, it returns the private key with which an Edge can be created using EdgeBuilder.

pub fn decrypt_direct(&self, key: &PrivateKey) -> Result<Vertex>

Decrypts the vertex with the knowledge of the ephemeral key.

pub fn decrypt(&self, master: &PrivateKey) -> Result<Vertex>

Decrypts this Vertex to a primitives::Vertex if master is listed in the access control list.

Otherwise Err(ring::error::Unspecified) is returned

fn acl<'s>(&'s self) -> impl Iterator<Item = &PublicKey> + 's

fn acl_cek_iter<'s>(
    &'s self
) -> impl Iterator<Item = (&PublicKey, &Vec<u8>)> + 's

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

Serializes the edge.

pub fn from_bytes(s: &[u8]) -> Result<Vertex, CryptoGraphError>

Deserializes the edge.

pub fn identifier(&self) -> [u8; 32]

Return the identifier

pub fn owner_bytes(&self) -> [u8; 32]

Trait Implementations

impl AsOwner for Vertex

fn as_owner_bytes(&self) -> [u8; 32]

impl Clone for Vertex

fn clone(&self) -> Vertex

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Vertex

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

Formats the value using the given formatter.

impl<'s> Deserialize<'s> for Vertex

fn deserialize<D: Deserializer<'s>>(deser: D) -> Result<Vertex, D::Error>

Deserialize this value from the given Serde deserializer.

impl Serialize for Vertex

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

Serialize this value into the given Serde serializer.
