Struct TransactionRequest 

#[non_exhaustive]
pub struct TransactionRequest {
    pub dataspaces: Vec<String>,
    pub read_only: bool,
    pub message: String,
}

What ETP’s StartTransaction asks for.

Built with TransactionRequest::new; #[non_exhaustive].

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

dataspaces: Vec<String>

The dataspaces the transaction covers. Empty: the writer’s own.

read_only: bool

A transaction that only reads (a consistent view), writing nothing.

message: String

What the transaction is for, as the caller words it.
