Enum AccountMode 

#[repr(u8)]
pub enum AccountMode {
    Placeholder = 0,
    ReadOnly = 1,
    System = 2,
    Delegated = 3,
    Ephemeral = 4,
    Transient = 5,
    Closed = 255,
}

Mutually exclusive modes an account can occupy in the ephemeral rollup (ER).

Variants

Placeholder = 0

Empty account (not found on chain) used to avoid frequent chain syncs.

ReadOnly = 1

Not writable by users (exists on chain, but not delegated)

System = 2

Internal account used for sysvars, features, and precompiles.

Delegated = 3

Account delegated to the current ER node instance.

Ephemeral = 4

Account that exists only inside the ER.

Transient = 5

Temporary state during mode transitions (e.g. delegated -> readonly).

Closed = 255

Closed account that should be removed from storage.

Implementations

impl AccountMode

pub fn allows_transition(self, to: Self, from_slot: Slot, to_slot: Slot) -> bool

Returns whether a privileged lifecycle operation may apply to at to_slot, including same-mode refreshes and slot ordering.

Only placeholder, read-only, and system accounts permit same-mode refreshes, and those require a newer slot. Slots may never regress.

pub fn mutable(&self) -> bool

Returns true for modes that may be mutated by user programs.

pub fn authoritative(&self) -> bool

Returns true for modes whose state is authoritative in this engine.

Trait Implementations

impl Clone for AccountMode

fn clone(&self) -> AccountMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AccountMode

impl Debug for AccountMode

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

Formats the value using the given formatter.

impl Default for AccountMode

fn default() -> AccountMode

Returns the “default value” for a type.

impl Eq for AccountMode

impl PartialEq for AccountMode

fn eq(&self, other: &AccountMode) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
