Dynamo Codegen

Python code generator for Dynamo Python bindings.

gen-python-prometheus-names

Generates prometheus_names.py from Rust source lib/runtime/src/metrics/prometheus_names.rs.

Usage

cargo run -p dynamo-codegen --bin gen-python-prometheus-names

What it does

• Parses Rust AST from lib/runtime/src/metrics/prometheus_names.rs
• Generates Python classes with constants at lib/bindings/python/src/dynamo/prometheus_names.py
• Handles macro-generated constants (e.g., kvstats_name!("active_blocks") → "kvstats_active_blocks")

Example

Rust input:

pub mod kvstats {
    pub const ACTIVE_BLOCKS: &str = kvstats_name!("active_blocks");
}

Python output:

class kvstats:
    ACTIVE_BLOCKS = "kvstats_active_blocks"

When to run

Run after modifying lib/runtime/src/metrics/prometheus_names.rs to regenerate the Python file.
