Trait MsgHandler 

pub trait MsgHandler {
    // Required methods
    fn get_msg_sender(&self, snapshot_id: usize) -> Result<DynSolValue>;
    fn get_msg_value(&self, snapshot_id: usize) -> Result<DynSolValue>;
}

Handler trait for msg global variables.

Provides access to transaction context variables like msg.sender and msg.value.

Required Methods

fn get_msg_sender(&self, snapshot_id: usize) -> Result<DynSolValue>

Get the message sender address (msg.sender).

Arguments

• snapshot_id - The execution context identifier

Returns

The sender address as a DynSolValue::Address

fn get_msg_value(&self, snapshot_id: usize) -> Result<DynSolValue>

Get the message value (msg.value).

Arguments

• snapshot_id - The execution context identifier

Returns

The message value in wei as a DynSolValue::Uint
