Struct BlockIndex

pub struct BlockIndex {
    pub starting_number: BlockNumber,
    pub offsets: Vec<i64>,
}

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

Fields

starting_number: BlockNumber

Starting block number

offsets: Vec<i64>

Offsets to data at each block number

Implementations

impl BlockIndex

pub const fn new(starting_number: BlockNumber, offsets: Vec<i64>) -> Self

Create a new BlockIndex

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

Get the offset for a specific block number

pub fn to_entry(&self) -> Entry

Convert to an Entry for storage in an e2store file

pub 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.
