Struct litetx::Header

pub struct Header {
    pub flags: HeaderFlags,
    pub page_size: PageSize,
    pub commit: PageNum,
    pub min_txid: TXID,
    pub max_txid: TXID,
    pub timestamp: SystemTime,
    pub pre_apply_checksum: Option<Checksum>,
}

An LTX file header.

Fields

flags: HeaderFlags

Flags changing the behavior of LTX encoder/decoder.

page_size: PageSize

The size of the database pages encoded in the file.

commit: PageNum

The size of the database in pages.

min_txid: TXID

Minimum transaction ID in the file.

max_txid: TXID

Maximum transaction ID in the file. May be equal to min_txid if the file contains only one transaction.

timestamp: SystemTime

The time when the LTX file was created.

pre_apply_checksum: Option<Checksum>

Running database checksum before this LTX file is applied. None if the LTX file contains the full snapshot of a database.

Trait Implementations

impl Clone for Header

fn clone(&self) -> Header

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Header

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

Formats the value using the given formatter.

impl PartialEq<Header> for Header

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