Struct ChangesetHeader 

pub struct ChangesetHeader {
    pub magic: [u8; 4],
    pub version: u16,
    pub page_size: u32,
    pub n_pages: u32,
    pub total_len: u64,
}

Self-delimiting changeset header (§3.4.2).

Fields

magic: [u8; 4]

version: u16

page_size: u32

n_pages: u32

total_len: u64

Implementations

impl ChangesetHeader

pub fn to_bytes(&self) -> [u8; 22]

Encode to little-endian bytes.

pub fn from_bytes(buf: &[u8; 22]) -> Result<Self>

Decode from little-endian bytes.

Errors

Returns error if magic or version mismatch.

Trait Implementations

impl Clone for ChangesetHeader

fn clone(&self) -> ChangesetHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChangesetHeader

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

Formats the value using the given formatter.

impl PartialEq for ChangesetHeader

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