Struct ReservedAccountKeys

pub struct ReservedAccountKeys {
    pub active: HashSet<Pubkey>,
    /* private fields */
}

ReservedAccountKeys holds the set of currently active/inactive account keys that are reserved by the protocol and may not be write-locked during transaction processing.

Fields

active: HashSet<Pubkey>

Set of currently active reserved account keys

Implementations

impl ReservedAccountKeys

pub fn new_all_activated() -> Self

Compute a set with all reserved keys active, regardless of whether their feature was activated. This is not to be used by the runtime. Useful for off-chain utilities that need to filter out reserved accounts.

pub fn is_reserved(&self, key: &Pubkey) -> bool

Returns whether the specified key is reserved

pub fn update_active_set(&mut self, feature_set: &FeatureSet)

Move inactive reserved account keys to the active set if their feature is active.

pub fn all_keys_iter() -> impl Iterator<Item = &'static Pubkey>

Return an iterator over all active / inactive reserved keys. This is not to be used by the runtime. Useful for off-chain utilities that need to filter out reserved accounts.

pub fn empty_key_set() -> HashSet<Pubkey>

Return an empty set of reserved keys for visibility when using in tests where the dynamic reserved key set is not available

Trait Implementations

impl Clone for ReservedAccountKeys

fn clone(&self) -> ReservedAccountKeys

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ReservedAccountKeys

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

Formats the value using the given formatter.

impl Default for ReservedAccountKeys

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for ReservedAccountKeys

fn eq(&self, other: &ReservedAccountKeys) -> 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.
