Struct BlockIndex 

pub struct BlockIndex { /* private fields */ }

BlockIndex records store offsets to data at specific block numbers from the beginning of the index record to the beginning of the corresponding data.

Format: starting-(block)-number | index | index | index ... | count

Implementations

impl BlockIndex

pub fn offset_for_block(&self, block_number: BlockNumber) -> Option<i64>

Get the offset for a specific block number

Trait Implementations

impl Clone for BlockIndex

fn clone(&self) -> BlockIndex

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockIndex

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

Formats the value using the given formatter.

impl IndexEntry for BlockIndex

fn new(starting_number: u64, offsets: Vec<i64>) -> Self

Create a new instance with starting number and offsets

fn entry_type() -> [u8; 2]

Get the entry type identifier for this index

fn starting_number(&self) -> u64

Get the starting number - can be starting slot or block number for example

fn offsets(&self) -> &[i64]

Get the offsets vector

fn to_entry(&self) -> Entry

Convert to an Entry for storage in an e2store file Format: starting-number | offset1 | offset2 | … | count

fn from_entry(entry: &Entry) -> Result<Self, E2sError>

Create from an Entry

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
