pub enum AnyTxEnvelope {
    Ethereum(TxEnvelope),
    Unknown(UnknownTxEnvelope),
}

Implementations

impl AnyTxEnvelope

pub const fn is_ethereum(&self) -> bool

Returns true if this is the ethereum transaction variant

pub const fn is_unknown(&self) -> bool

Returns true if this is the unknown transaction variant

pub const fn as_envelope(&self) -> Option<&TxEnvelope>

Returns the inner Ethereum transaction envelope, if it is an Ethereum transaction.

pub const fn as_unknown(&self) -> Option<&UnknownTxEnvelope>

Returns the inner UnknownTxEnvelope if it is an unknown variant.

pub fn try_into_envelope(self) -> Result<TxEnvelope, ValueError<Self>>

Returns the inner Ethereum transaction envelope, if it is an Ethereum transaction. If the transaction is not an Ethereum transaction, it is returned as an error.

pub fn try_into_unknown(self) -> Result<UnknownTxEnvelope, Self>

Returns the inner UnknownTxEnvelope, if it is an unknown transaction. If the transaction is not an unknown transaction, it is returned as an error.

pub fn try_into_either<T>(self) -> Result<Either<TxEnvelope, T>, T::Error>

where T: TryFrom<UnknownTxEnvelope>,

Attempts to convert the UnknownTxEnvelope into Either::Right if this is an unknown variant.

Returns Either::Left with the ethereum TxEnvelope if this is the AnyTxEnvelope::Ethereum variant and Either::Right with the converted variant.

Examples

match envelope.try_into_either::<CustomTx>()? {
    Either::Left(eth_tx) => { /* Ethereum transaction */ }
    Either::Right(custom_tx) => { /* Custom transaction */ }
}

pub fn try_map_unknown<T, E>( self, f: impl FnOnce(UnknownTxEnvelope) -> Result<T, E>, ) -> Result<Either<TxEnvelope, T>, E>

Attempts to convert the UnknownTxEnvelope into Either::Right if this is an AnyTxEnvelope::Unknown.

Returns Either::Left with the ethereum TxEnvelope if this is the AnyTxEnvelope::Ethereum variant and Either::Right with the converted variant.

Use this for custom conversion logic when try_into_either is insufficient.

Examples

let result = envelope.try_map_unknown(|unknown| Ok::<B256, String>(unknown.hash))?;
match result {
    Either::Left(eth_tx) => { /* Ethereum */ }
    Either::Right(hash) => { /* Unknown tx hash */ }
}
