Enum solana_accounts_db::tiered_storage::owners::OwnersBlockFormat

#[repr(u16)]
pub enum OwnersBlockFormat {
    AddressesOnly = 0,
}

Owner block holds a set of unique addresses of account owners, and an account meta has a owner_offset field for accessing it’s owner address.

Variants

AddressesOnly = 0

This format persists OwnerBlock as a consecutive bytes of pubkeys without any meta-data. For each account meta, it has a owner_offset field to access its owner’s address in the OwnersBlock.

Implementations

impl OwnersBlockFormat

pub fn write_owners_block( &self, file: &TieredStorageFile, addresses: &[Pubkey] ) -> TieredStorageResult<usize>

Persists the provided owners’ addresses into the specified file.

pub fn get_owner_address<'a>( &self, mmap: &'a Mmap, footer: &TieredStorageFooter, owner_offset: OwnerOffset ) -> TieredStorageResult<&'a Pubkey>

Returns the owner address associated with the specified owner_offset and footer inside the input mmap.

Trait Implementations

impl Clone for OwnersBlockFormat

fn clone(&self) -> OwnersBlockFormat

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OwnersBlockFormat

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

Formats the value using the given formatter.

impl Default for OwnersBlockFormat

fn default() -> OwnersBlockFormat

Returns the “default value” for a type.

impl From<OwnersBlockFormat> for u16

fn from(enum_value: OwnersBlockFormat) -> Self

Converts to this type from the input type.

impl Hash for OwnersBlockFormat

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for OwnersBlockFormat

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<u16> for OwnersBlockFormat

type Error = TryFromPrimitiveError<OwnersBlockFormat>

The type returned in the event of a conversion error.

fn try_from(number: u16) -> Result<Self, TryFromPrimitiveError<Self>>

Performs the conversion.

impl TryFromPrimitive for OwnersBlockFormat

type Primitive = u16

type Error = TryFromPrimitiveError<OwnersBlockFormat>

const NAME: &'static str = "OwnersBlockFormat"

fn try_from_primitive( number: Self::Primitive ) -> Result<Self, TryFromPrimitiveError<Self>>
