Struct Era1Id 

pub struct Era1Id {
    pub network_name: String,
    pub start_block: BlockNumber,
    pub block_count: u32,
    pub hash: Option<[u8; 4]>,
}

Era1 file identifier

Fields

network_name: String

Network configuration name

start_block: BlockNumber

First block number in file

block_count: u32

Number of blocks in the file

hash: Option<[u8; 4]>

Optional hash identifier for this file First 4 bytes of the last historical root in the last state in the era file

Implementations

impl Era1Id

pub fn new( network_name: impl Into<String>, start_block: BlockNumber, block_count: u32, ) -> Self

Create a new Era1Id

pub const fn with_hash(self, hash: [u8; 4]) -> Self

Add a hash identifier to Era1Id

Trait Implementations

impl Clone for Era1Id

fn clone(&self) -> Era1Id

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Era1Id

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

Formats the value using the given formatter.

impl EraFileId for Era1Id

fn to_file_name(&self) -> String

Convert to file name following the era file naming: <config-name>-<era-number>-<era-count>-<short-historical-root>.era(1) https://github.com/eth-clients/e2store-format-specs/blob/main/formats/era.md#file-name See also https://github.com/eth-clients/e2store-format-specs/blob/main/formats/era1.md

fn network_name(&self) -> &str

Get the network name

fn start_number(&self) -> u64

Get the starting number (block or slot)

fn count(&self) -> u32

Get the count of items

impl PartialEq for Era1Id

fn eq(&self, other: &Era1Id) -> 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.

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.
