tendermint_proto

Re-export of tendermint-proto v0.37

time

Types for dealing with time and durations.

token

Shielded and transparent tokens related functions

transaction

Data-Types that are used in transactions.

uint

An unsigned 256 integer type. Used for, among other things, the backing type of token amounts.

validity_predicate

Types that are used in validity predicates.

voting_power

This module contains types related with validator voting power calculations.

Macros

debug_log

Format and log a string in a debug build.

impl_display_and_from_str_via_format

Implement std::fmt::Display and std::str::FromStr via Format.

Structs

BatchedTx

A transaction with the commitment to a specific inner transaction of the batch

BlockHash

Hash of a block as fixed-size byte array

BlockHeader

The block header data from Tendermint header relevant for Namada storage

BlockHeight

Height of a block, i.e. the level. The default is the BlockHeight::sentinel value, which doesn’t correspond to any block.

Ctx

Execution context provides access to the host environment functions

Epoch

Epoch identifier. Epochs are identified by consecutive numbers.

EthAddress

Representation of address on Ethereum. The inner value is the last 20 bytes of the public key that controls the account.

Event

Custom events that can be queried from Tendermint using a websocket client

EventType

ABCI event type.

KeyValIterator

Storage key-val pair iterator

Log

Extend an Event with log data.

Tx

A Namada transaction is represented as a header followed by a series of sections providing additional details.

Enums

Address

An account’s address

DecodeError

Error

EventLevel

Indicates if an event is emitted do to an individual Tx or the nature of a finalized block

Section

A section of a transaction. Carries an independent piece of information necessary for the processing of a transaction.

Constants

BLOCK_HASH_LENGTH

The length of the block hash

Traits

BorshDeserialize

A data-structure that can be de-serialized from binary format by NBOR.

BorshSerialize

A data-structure that can be serialized into binary format by NBOR.

BorshSerializeExt

Extensions to types implementing BorshSerialize.

EmitEvents

Used in sub-systems that may emit events.

EventToEmit

An event to be emitted in Namada.

OptionExt

An extension to Option to allow turning None case to an Error from a static string (handy for WASM).

ResultExt

Result extension to easily wrap custom errors into Error.

StorageRead

Common storage read interface
