Overview

The Core module provides fundamental system types, errors, and constants for Tetcore.

Chain Types

ChainId

pub struct ChainId(pub u32);

SystemVersion

pub struct SystemVersion(pub u32);

CoreChainType

pub enum CoreChainType {
    Development,
    Local,
    Testnet,
    Mainnet,
}

Block Types

BlockNumber

pub struct BlockNumber(pub u64);

Nonce

pub struct Nonce(pub u64);

Errors

SystemErrorKind

pub enum SystemErrorKind {
    Unknown,
    InvalidTransaction,
    InvalidSignature,
    InsufficientFunds,
    InsufficientGas,
    NonceTooLow,
    NonceTooHigh,
    ChainIdMismatch,
    InvalidBlock,
    InvalidState,
    StorageOverflow,
    StorageUnderflow,
    ModuleNotFound,
    MethodNotFound,
    CallFailed,
    ContractNotFound,
    // ... more variants
}

Events

EventPhase

pub enum EventPhase {
    Initialization,
    ApplyExtrinsic(u32),
    Finalization,
}

SystemEventType

pub enum SystemEventType {
    ExtrinsicSuccess,
    ExtrinsicFailed { error: SystemError },
    CodeUpdated,
    RuntimeUpdated,
    NewAccount { account: Address },
    KilledAccount { account: Address },
    Transfer { from: Address, to: Address, amount: u128 },
    // ... more variants
}

Runtime
