Struct RuleSetHeader

pub struct RuleSetHeader {
    pub key: Key,
    pub rev_map_version_location: usize,
}

Header used to keep track of where RuleSets are stored in the PDA. This header is meant to be stored at the beginning of the PDA and never be versioned so that it always has the same serialized size. See top-level module for description of PDA memory layout.

Fields

key: Key

The Key for this account which identifies it as a RuleSet account.

rev_map_version_location: usize

The location of revision map version stored in the PDA. This is one byte before the revision map itself.

Implementations

impl RuleSetHeader

pub fn new(rev_map_version_location: usize) -> Self

Create a new RuleSetHeader.

Trait Implementations

impl BorshDeserialize for RuleSetHeader

where Key: BorshDeserialize, usize: BorshDeserialize,

fn deserialize_reader<R: Read>(reader: &mut R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for RuleSetHeader

where Key: BorshSerialize, usize: BorshSerialize,

fn serialize<W: Write>(&self, writer: &mut W) -> Result<(), Error>

fn try_to_vec(&self) -> Result<Vec<u8>, Error>

Serialize this instance into a vector of bytes.

impl Clone for RuleSetHeader

fn clone(&self) -> RuleSetHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RuleSetHeader

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

Formats the value using the given formatter.

impl PartialEq for RuleSetHeader

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