Module read 

Streaming reader for e2store-based file formats.

Provides three levels of abstraction over raw e2store entries:

1. Raw entries - E2StoreReader in format::e2store (type + bytes)
2. Typed entries - EraReader yields TypedEntry with decoded payloads
3. Block assembly - EraBlockReader combines related entries into complete blocks

Additionally, EraRandomReader provides seek-based random access by slot number.

Format Detection

The reader auto-detects whether a file is ERA (post-merge) or ERA1 (pre-merge) based on the first non-version entry type.

Structs

Era1Block

A fully-assembled ERA1 block.

EraBlock

A fully-assembles ERA block.

EraBlockReader

Block-level reader that assembles related entries into complete blocks.

EraRandomReader

Random-access reader for ERA/ERA1 files.

EraReader

Streaming reader that yields typed entries from an ERA/ERA1 file.

Enums

Block

An assembled block from either format.

EraFormat

Detected file format.

SlotLookupError

Error when a slot lookup fails

TypedEntry

A types, decoded e2store entry.

Functions

iter_blocks

Iterate over blocks in raw file bytes without allocating Entry structs.
