Implementations

impl HeaderNode

pub fn default() -> Self

pub fn serialize_into(&self, buf: &mut [u8]) -> usize

Writes the serialized HeaderNode into the provided buffer and returns the number of bytes written (48). The buffer must be at least 48 bytes long.

pub fn from_slice(slice: &[u8]) -> DCBResult<Self>

Creates a HeaderNode from a byte slice Expects a slice with 48 bytes:

• 8 bytes for tsn
• 8 bytes for next_page_id
• 8 bytes for free_lists_tree_root_id
• 8 bytes for events_tree_root_id
• 8 bytes for tags_tree_root_id
• 8 bytes for next_position

Arguments

• slice - The byte slice to deserialize from

Returns

• Result<Self> - The deserialized HeaderNode or an error

Trait Implementations

impl Clone for HeaderNode

fn clone(&self) -> HeaderNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HeaderNode

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

Formats the value using the given formatter.

impl PartialEq for HeaderNode

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