Struct DeriveCredential 

pub struct DeriveCredential { /* private fields */ }

Derive Chain smart-contract wallet + session-key + subaccount triple.

Implementations

impl DeriveCredential

pub fn new( wallet_address: String, session_key: String, subaccount_id: u64, ) -> Self

Creates a new DeriveCredential instance.

pub fn wallet_address(&self) -> &str

Returns the Derive Chain smart-contract wallet address (X-LYRAWALLET).

pub fn session_key(&self) -> &str

Returns the secp256k1 session-key private key (hex-encoded).

pub const fn subaccount_id(&self) -> u64

Returns the subaccount integer ID.

pub fn resolve( wallet_address: Option<String>, session_key: Option<String>, subaccount_id: Option<u64>, environment: DeriveEnvironment, ) -> Result<Self>

Resolves a DeriveCredential from explicit values, falling back to the documented environment variables when fields are unset.

Resolution order per field is: explicit value, then env var. The env var name set is selected by environment via credential_env_vars.

Errors

Returns an error when any of the wallet address, session key, or subaccount ID cannot be resolved from either source, or when the subaccount id env var is not a valid u64.

Trait Implementations

impl Clone for DeriveCredential

fn clone(&self) -> DeriveCredential

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeriveCredential

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

Formats the value using the given formatter.

impl Display for DeriveCredential

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

Formats the value using the given formatter.

impl Drop for DeriveCredential

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Zeroize for DeriveCredential

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
