Trait IndexEntry 

pub trait IndexEntry: Sized {
    // Required methods
    fn entry_type() -> [u8; 2];
    fn new(starting_number: u64, offsets: Vec<i64>) -> Self;
    fn starting_number(&self) -> u64;
    fn offsets(&self) -> &[i64];

    // Provided methods
    fn to_entry(&self) -> Entry { ... }
    fn from_entry(entry: &Entry) -> Result<Self, E2sError> { ... }
}

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

Required Methods

fn entry_type() -> [u8; 2]

Get the entry type identifier for this index

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

Create a new instance with starting number and offsets

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

Provided Methods

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

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
