Crate relay_utils

Utilities used by different relays.

Re-exports

• pub use error::Error;
• pub use relay_loop::relay_loop;
• pub use relay_loop::relay_metrics;

Modules

• error
• initialize
  Relayer initialization functions.
• metrics
• relay_loop

Macros

• bail_on_arg_error
  Macro that returns (client, Err(error)) tuple from function if result is Err(error).
• bail_on_error
  Macro that returns (client, Err(error)) tuple from function if result is Err(error).

Structs

• HeaderId
  Generic header Id.

Enums

• FailedClient
  Which client has caused error.
• ProcessFutureResult
  Future process result.
• StringifiedMaybeConnectionError
  Stringified error that may be either connection-related or not.
• TrackedTransactionStatus
  Final status of the tracked transaction.

Constants

• CONNECTION_ERROR_DELAY
  Delay after connection-related error happened before we’ll try reconnection again.
• MAX_BACKOFF_INTERVAL
  Max delay after connection-unrelated error happened before we’ll try the same request again.
• STALL_TIMEOUT
  Default relay loop stall timeout. If transactions generated by relay are immortal, then this timeout is used.

Traits

• BlockNumberBase
  Block number traits shared by all chains that relay is able to serve.
• MaybeConnectionError
  Error type that can signal connection errors.
• TransactionTracker
  Transaction tracker.
• UniqueSaturatedFrom
  Just like From except that if the source value is too big to fit into the destination type then it’ll saturate the destination.
• UniqueSaturatedInto
  Just like Into except that if the source value is too big to fit into the destination type then it’ll saturate the destination.

Functions

• format_ids
  Compact format of IDs vector.
• interval
  Stream that emits item every timeout_ms milliseconds.
• process_future_result
  Process result of the future from a client.
• retry_backoff
  Exponential backoff for connection-unrelated errors retries.

Type Aliases

• TrackedTransactionFuture
  Future associated with TransactionTracker, monitoring the transaction status.
