Struct SegmentMeta 

pub struct SegmentMeta {
    pub path: PathBuf,
    pub first_lsn: u64,
    pub file_size: u64,
}

Metadata about a WAL segment file on disk.

Fields

path: PathBuf

Path to the segment file on disk.

first_lsn: u64

First LSN stored in this segment (from the filename).

file_size: u64

File size in bytes.

Implementations

impl SegmentMeta

pub fn dwb_path(&self) -> PathBuf

Path to the companion double-write buffer file.

Trait Implementations

impl Clone for SegmentMeta

fn clone(&self) -> SegmentMeta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SegmentMeta

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

Formats the value using the given formatter.

impl Ord for SegmentMeta

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for SegmentMeta

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

impl PartialOrd for SegmentMeta

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
