Trait InstructionProvider 

pub trait InstructionProvider: Send + Sync {
    // Required method
    fn provide(&self, state: &State) -> String;
}

A dynamic instruction source — the ADK “instruction provider” pattern: instead of a string fixed at build time, the instruction is produced from live session state on every model request (persona switching, risk-driven guardrails, multi-tenant instructions without rebuilding the agent). Any Fn(&State) -> String closure is a provider.

Required Methods

fn provide(&self, state: &State) -> String

Produce the system instruction for the current request.

Dyn Compatibility

This trait is dyn compatible.

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