Enum SemioscanError 

pub enum SemioscanError {
    BlockWindow(BlockWindowError),
    Gas(GasCalculationError),
    Price(PriceCalculationError),
    Events(EventProcessingError),
    Retrieval(RetrievalError),
}

Unified error type for all semioscan operations.

This enum wraps all module-specific error types, providing a convenient way to handle errors when you don’t need to distinguish between different error sources.

All module-specific error types automatically convert to SemioscanError via From implementations, so you can use ? to propagate errors naturally.

Examples

use semioscan::{SemioscanError, BlockWindowCalculator, GasCostCalculator};
use alloy_chains::NamedChain;
use chrono::NaiveDate;

async fn process_data() -> Result<(), SemioscanError> {
    let block_calc = BlockWindowCalculator::with_disk_cache(provider, "cache.json")?;
    let gas_calc = GasCostCalculator::new(provider);

    // Both error types automatically convert to SemioscanError
    let date = NaiveDate::from_ymd_opt(2024, 1, 15).unwrap();
    let window = block_calc.get_daily_window(NamedChain::Arbitrum, date).await?;
    let gas_cost = gas_calc.calculate_gas_cost_for_transfers_between_blocks(
        NamedChain::Arbitrum, from_address, to_address, token_address, start_block, end_block
    ).await?;

    Ok(())
}

Variants

Trait Implementations

impl Debug for SemioscanError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for SemioscanError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for SemioscanError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
