Struct AuthorizedKey 

pub struct AuthorizedKey {
    pub signature_type: u8,
    pub expiry: u64,
    pub enforce_limits: bool,
    pub is_revoked: bool,
}

Key information stored in the precompile

Storage layout (packed into single slot, right-aligned):

• byte 0: signature_type (u8)
• bytes 1-8: expiry (u64, little-endian)
• byte 9: enforce_limits (bool)
• byte 10: is_revoked (bool)

Fields

signature_type: u8

Signature type: 0 = secp256k1, 1 = P256, 2 = WebAuthn

expiry: u64

Block timestamp when key expires

enforce_limits: bool

Whether to enforce spending limits for this key

is_revoked: bool

Whether this key has been revoked. Once revoked, a key cannot be re-authorized with the same key_id. This prevents replay attacks.

Implementations

impl AuthorizedKey

pub fn decode_from_slot(slot_value: U256) -> Self

Decode AuthorizedKey from a storage slot value

This is useful for read-only contexts (like pool validation) that don’t have access to PrecompileStorageProvider but need to decode the packed struct.

Trait Implementations

impl Clone for AuthorizedKey

fn clone(&self) -> AuthorizedKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AuthorizedKey

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

Formats the value using the given formatter.

impl Default for AuthorizedKey

fn default() -> AuthorizedKey

Returns the “default value” for a type.

impl PartialEq for AuthorizedKey

fn eq(&self, other: &AuthorizedKey) -> 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 Storable<Storable> for AuthorizedKey

fn load<S: StorageOps>( storage: &mut S, base_slot: U256, ctx: LayoutCtx, ) -> Result<Self>

Load this type from storage starting at the given base slot.

fn store<S: StorageOps>( &self, storage: &mut S, base_slot: U256, ctx: LayoutCtx, ) -> Result<()>

Store this type to storage starting at the given base slot.

fn to_evm_words(&self) -> Result<[U256; 1]>

Encode this type to an array of U256 words.

fn from_evm_words(words: [U256; 1]) -> Result<Self>

Decode this type from an array of U256 words.

fn delete<S: StorageOps>( storage: &mut S, base_slot: U256, ctx: LayoutCtx, ) -> Result<()>

Delete this type from storage (set all slots to zero).

fn validate_layout()

Test helper to ensure LAYOUT and SLOTS are in sync.

impl StorableType for AuthorizedKey

const LAYOUT: Layout

Describes how this type is laid out in storage.

const SLOTS: usize = _

Number of storage slots this type takes.

const BYTES: usize = _

Number of bytes this type takes.

const IS_PACKABLE: bool = _

Whether this type can be packed with adjacent fields.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
