Fields

shard_name: String

Shard file name (e.g., "2026-01.events").

event_count: u64

Number of event lines (excluding comments and blanks).

byte_len: u64

Total byte length of the shard file.

file_hash: String

BLAKE3 hash of the entire shard file contents.

Implementations

impl ShardManifest

pub fn to_string_repr(&self) -> String

Serialize manifest to a human-readable format.

pub fn from_string_repr(s: &str) -> Option<Self>

Parse a manifest from its string representation.

Returns None if required fields are missing or unparseable.

Trait Implementations

impl Clone for ShardManifest

fn clone(&self) -> ShardManifest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShardManifest

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

Formats the value using the given formatter.

impl PartialEq for ShardManifest

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