Trait TxFnExpander 

Source 
pub trait TxFnExpander: Send + Sync {
    // Required method
    fn expand(&self, db: &Db, forms: Vec<Edn>) -> Result<Vec<Edn>, String>;
}
Expand description

Expands user database-function invocations in boundary EDN transaction forms before native conversion. The built-in implementation is crate::txfn::DbFnExpander on the bounded cljrs-tx runtime (feature cljrs, on by default, ADR-0008); embedders may inject their own.

Required Methods§

Source

fn expand(&self, db: &Db, forms: Vec<Edn>) -> Result<Vec<Edn>, String>

Rewrites forms with every [:my/fn arg…] invocation replaced by the function’s returned tx-data (recursively).

§Errors

Returns a display message when a function is missing, rejected by the sandbox, fails, or exceeds its budget; the transaction aborts.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
