Expand description

Serialize and deserialize index entries with format: starting-number | offsets... | count

Required Methods§

Source

fn entry_type() -> [u8; 2]

Get the entry type identifier for this index

Source

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

Create a new instance with starting number and offsets

Source

fn starting_number(&self) -> u64

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

Source

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

Get the offsets vector

Provided Methods§

Source

fn to_entry(&self) -> Entry

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

Source

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

Create from an Entry

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
