Crate linera_chain 

This module manages the state of a Linera chain, including cross-chain communication.

Modules

block

Block types and the wrappers that pair them with their execution outcomes.

data_types

Data types exchanged while proposing, voting on, and confirming blocks.

justification

Fault attributability

manager

Chain manager

test

Test utilities

types

Convenience re-exports of the public block and certificate types.

Structs

ChainIdSet

A set of fully-tracked chains. Wrapped in Hashed (as Hashed<ChainIdSet>) so the hash that identifies the set — stored in ChainStateView::outbox_index_tracked_hash to detect when the outbox indices must be reconciled — is computed once when the tracked set changes rather than on every cross-chain operation. The hash is order-independent because BTreeSet iterates in sorted order.

ChainStateView

A view accessing the state of a chain.

ChainTipState

Block-chaining state.

StreamCounts

The event indices we track for a stream, maintained whenever a block is processed (executed or merely preprocessed).

Enums

BlockExecutionPhase

The protocol phase a block is executed in. Recorded as the phase label on the block-execution metrics so the three distinct paths — staging a proposal, validating a received proposal, and committing a confirmed certificate — are separate time series in Prometheus.

ChainError

An error that occurred while validating or executing a block on a chain.

ChainExecutionContext

The phase of block execution during which an error occurred.

Traits

ExecutionResultExt

Extension trait for attaching a ChainExecutionContext to an execution error.
