Enum EraFileType 

pub enum EraFileType {
    Era,
    Era1,
    Ere,
}

Era file type identifier

Variants

Era

Consensus layer ERA file, .era Contains beacon blocks and states

Era1

Execution layer ERA1 file, .era1 Contains execution blocks pre-merge

Ere

Execution layer ERE file, .ere Contains execution blocks for both pre-merge and post-merge

Implementations

impl EraFileType

pub const fn extension(&self) -> &'static str

Get the canonical file extension for this type, dot included.

Used when writing files. For recognizing downloaded files, which may use an alternate extension, see extensions.

pub const fn extensions(&self) -> &'static [&'static str]

All file extensions this type may be published with, dot included, ordered longest-first.

ere files are served as either .erae (current ethPandaOps naming) or .ere. The longest-first order matters for substring scans so .ere never matches inside .erae.

pub const fn has_checksums(&self) -> bool

Whether files of this type are published with a checksums.txt for verification.

Execution-layer files (era1, ere) ship checksums; consensus-layer era files do not.

pub fn from_filename(filename: &str) -> Option<Self>

Detect file type from a filename

pub fn format_filename( &self, network_name: &str, era_number: u64, hash: Option<[u8; 4]>, include_era_count: bool, era_count: u64, ) -> String

Generate era file name.

Standard format: <config-name>-<era-number>-<short-historical-root>.<ext> See also https://github.com/eth-clients/e2store-format-specs/blob/main/formats/era.md#file-name

With era count (for custom exports): <config-name>-<era-number>-<era-count>-<short-historical-root>.<ext>

pub fn from_dir(dir: impl AsRef<Path>) -> Result<Option<Self>>

Detects the execution-layer file type from the files in dir.

Returns the type of the first .era1 or .ere/.erae file found. Consensus-layer .era files are ignored.

pub fn from_url(url: &str) -> Self

Detect file type from a URL, defaulting to Era.

Resolves by file extension when the URL names a file; otherwise falls back to the era1 host/path substring.

Trait Implementations

impl Clone for EraFileType

fn clone(&self) -> EraFileType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for EraFileType

impl Debug for EraFileType

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

Formats the value using the given formatter.

impl Eq for EraFileType

impl Hash for EraFileType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for EraFileType

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

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.
