Fields

version: u8

Version identifier

bump: u8

Bump

nonce: u64

Nonce, for protecting against replay attacks around secp256k1 signatures.

initial_verification_method: VerificationMethod

The initial authority key, automatically being added to the array of all Verification Methods.

verification_methods: Vec<VerificationMethod>

All verification methods

services: Vec<Service>

Services

native_controllers: Vec<Pubkey>

Controller (native) - did:sol:

other_controllers: Vec<String>

Controller (others) - all others

Implementations

impl DidAccount

pub fn new(bump: u8, authority_key: &Pubkey) -> Self

pub fn init(
    &mut self,
    bump: u8,
    authority_key: &Pubkey,
    flags: VerificationMethodFlags
)

pub fn verification_methods(
    &self,
    filter_types: Option<&[VerificationMethodType]>,
    filter_flags: Option<VerificationMethodFlags>,
    filter_key: Option<&[u8]>,
    filter_fragment: Option<&String>
) -> Vec<&VerificationMethod>

Accessor for all verification methods (including the initial one) Enables to pass several filters that are ANDed together.

pub fn verification_methods_mut(
    &mut self,
    filter_types: Option<&[VerificationMethodType]>,
    filter_flags: Option<VerificationMethodFlags>,
    filter_key: Option<&[u8]>,
    filter_fragment: Option<&String>
) -> Vec<&mut VerificationMethod>

Accessor for all verification methods (including the initial one) Enables to pass several filters that are ANDed together. Mutable Version

pub fn remove_verification_method(&mut self, fragment: &String) -> Result<()>

pub fn find_verification_method(
    &mut self,

    filter_types: Option<&[VerificationMethodType]>,
    filter_fragment: Option<&String>

pub fn is_directly_controlled_by(&self, other: &DidAccount) -> bool

Returns true if other is a valid controller of this DID

pub fn is_controlled_by(&self, chain: &[Account<'_, DidAccount>]) -> bool

returns true if the controller chain is valid. The chain must be provided in the following order: this -> chain[0] -> … -> chain[n] where ‘->’ represents the relationship “is controlled by”. NOTE: an empty chain returns true.

Trait Implementations

impl AccountDeserialize for DidAccount

fn try_deserialize(buf: &mut &[u8]) -> Result<Self>

Deserializes previously initialized account data. Should fail for all uninitialized accounts, where the bytes are zeroed. Implementations should be unique to a particular account type so that one can never successfully deserialize the data of one account type into another. For example, if the SPL token program were to implement this trait, it should be impossible to deserialize a Mint account into a token Account.

fn try_deserialize_unchecked(buf: &mut &[u8]) -> Result<Self>

Deserializes account data without checking the account discriminator. This should only be used on account initialization, when the bytes of the account are zeroed.

impl AccountSerialize for DidAccount

fn try_serialize<W: Write>(&self, writer: &mut W) -> Result<()>

Serializes the account data into writer.

impl BorshDeserialize for DidAccountwhere
    u8: BorshDeserialize,
    u8: BorshDeserialize,
    u64: BorshDeserialize,
    VerificationMethod: BorshDeserialize,
    Vec<VerificationMethod>: BorshDeserialize,
    Vec<Service>: BorshDeserialize,
    Vec<Pubkey>: BorshDeserialize,
    Vec<String>: BorshDeserialize,

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

impl BorshSerialize for DidAccountwhere
    u8: BorshSerialize,
    u8: BorshSerialize,

fn serialize<W: Write>(&self, writer: &mut W) -> Result<(), Error>

fn try_to_vec(&self) -> Result<Vec<u8, Global>, Error>
