Trait TxEnvConverter 

pub trait TxEnvConverter<TxReq, TxEnv, Spec>:
    Debug
    + Send
    + Sync
    + Unpin
    + Clone
    + 'static {
    type Error;

    // Required method
    fn convert_tx_env(
        &self,
        tx_req: TxReq,
        cfg_env: &CfgEnv<Spec>,
        block_env: &BlockEnv,
    ) -> Result<TxEnv, Self::Error>;
}

Converts TxReq into TxEnv.

Where:

• TxReq is a transaction request received from an RPC API
• TxEnv is the corresponding transaction environment for execution

The TxEnvConverter has two blanket implementations:

• () assuming TxReq implements TryIntoTxEnv and is used as default for RpcConverter.
• Fn(TxReq, &CfgEnv<Spec>, &BlockEnv) -> Result<TxEnv, E> and can be applied using RpcConverter::with_tx_env_converter.

One should prefer to implement TryIntoTxEnv for TxReq to get the TxEnvConverter implementation for free, thanks to the blanket implementation, unless the conversion requires more context. For example, some configuration parameters or access handles to database, network, etc.

Required Associated Types

type Error

An associated error that can occur during conversion.

Required Methods

fn convert_tx_env( &self, tx_req: TxReq, cfg_env: &CfgEnv<Spec>, block_env: &BlockEnv, ) -> Result<TxEnv, Self::Error>

Converts a rpc transaction request into a transaction environment.

See TxEnvConverter for more information.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types

impl<TxReq, TxEnv, Spec> TxEnvConverter<TxReq, TxEnv, Spec> for ()

where TxReq: TryIntoTxEnv<TxEnv>,

type Error = <TxReq as TryIntoTxEnv<TxEnv>>::Err

fn convert_tx_env( &self, tx_req: TxReq, cfg_env: &CfgEnv<Spec>, block_env: &BlockEnv, ) -> Result<TxEnv, <() as TxEnvConverter<TxReq, TxEnv, Spec>>::Error>
