Also run cargo fmt to fix formatting. --- crates/quota-router-cli/src/lib.rs | 7 +----- crates/quota-router-pyo3/src/completion.rs | 25 ++++++---------------- crates/quota-router-pyo3/src/lib.rs | 2 ++ crates/quota-router-pyo3/src/types.rs | 21 +++++++++--------- 4 files changed, 20 insertions(+), 35 deletions(-) diff --git a/crates/quota-router-cli/src/lib.rs b/crates/quota-router-cli/src/lib.rs index 9d0416a..82cc701 100644 --- a/crates/quota-router-cli/src/lib.rs +++ b/crates/quota-router-cli/src/lib.rs @@ -1,12 +1,7 @@ // Quota Router CLI - Library // Re-exports from quota-router-core -pub use quota_router_core::{ - balance, - config, - providers, - proxy, -}; +pub use quota_router_core::{balance, config, providers, proxy}; pub mod cli; pub mod commands; diff --git a/crates/quota-router-pyo3/src/completion.rs b/crates/quota-router-pyo3/src/completion.rs index ea4c126..43352ab 100644 --- a/crates/quota-router-pyo3/src/completion.rs +++ b/crates/quota-router-pyo3/src/completion.rs @@ -1,6 +1,7 @@ // Completion functions for PyO3 bindings #![allow(clippy::too_many_arguments)] +#![allow(deprecated)] use crate::types::{ChatCompletion, Choice, Message}; use pyo3::prelude::*; @@ -45,11 +46,8 @@ pub fn completion( }) .collect(); - let response = ChatCompletion::new( - format!("chatcmpl-{}", uuid::Uuid::new_v4()), - model, - choices, - ); + let response = + ChatCompletion::new(format!("chatcmpl-{}", uuid::Uuid::new_v4()), model, choices); // Convert to Python dict let result = Python::with_gil(|py| response.to_dict(py))?; @@ -96,11 +94,8 @@ pub async fn acompletion( }) .collect(); - let response = ChatCompletion::new( - format!("chatcmpl-{}", uuid::Uuid::new_v4()), - model, - choices, - ); + let response = + ChatCompletion::new(format!("chatcmpl-{}", uuid::Uuid::new_v4()), model, choices); // Convert to Python dict Python::with_gil(|py| response.to_dict(py)) @@ -109,10 +104,7 @@ pub async fn acompletion( /// embedding - Sync embedding call #[pyfunction] #[pyo3(name = "embedding", text_signature = "(input, model, **kwargs)")] -pub fn embedding( - input: Vec, - model: String, -) -> PyResult> { +pub fn embedding(input: Vec, model: String) -> PyResult> { println!("embedding called: model={}, input={}", model, input.len()); // Mock embedding response @@ -167,10 +159,7 @@ pub fn embedding( /// aembedding - Async embedding call #[pyfunction] #[pyo3(name = "aembedding")] -pub async fn aembedding( - input: Vec, - model: String, -) -> PyResult> { +pub async fn aembedding(input: Vec, model: String) -> PyResult> { println!("aembedding called: model={}, input={}", model, input.len()); // Mock embedding response diff --git a/crates/quota-router-pyo3/src/lib.rs b/crates/quota-router-pyo3/src/lib.rs index 71b0e89..03165c6 100644 --- a/crates/quota-router-pyo3/src/lib.rs +++ b/crates/quota-router-pyo3/src/lib.rs @@ -1,6 +1,8 @@ // quota-router-pyo3 - Python bindings for quota-router // Enables drop-in replacement for LiteLLM +#![allow(deprecated)] + mod completion; mod exceptions; mod types; diff --git a/crates/quota-router-pyo3/src/types.rs b/crates/quota-router-pyo3/src/types.rs index 7e699bb..bf026d0 100644 --- a/crates/quota-router-pyo3/src/types.rs +++ b/crates/quota-router-pyo3/src/types.rs @@ -1,5 +1,7 @@ // Type definitions for PyO3 bindings +#![allow(deprecated)] + use pyo3::prelude::*; use pyo3::types::{PyDict, PyList}; use serde::{Deserialize, Serialize}; @@ -80,17 +82,10 @@ pub struct ChatCompletion { } impl ChatCompletion { - pub fn new( - id: impl Into, - model: impl Into, - choices: Vec, - ) -> Self { + pub fn new(id: impl Into, model: impl Into, choices: Vec) -> Self { let id = id.into(); let model = model.into(); - let total_tokens: u32 = choices - .iter() - .map(|c| c.message.content.len() as u32) - .sum(); + let total_tokens: u32 = choices.iter().map(|c| c.message.content.len() as u32).sum(); Self { id, @@ -122,10 +117,14 @@ impl ChatCompletion { let message_dict = PyDict::new(py); message_dict.set_item("role", &c.message.role).unwrap(); - message_dict.set_item("content", &c.message.content).unwrap(); + message_dict + .set_item("content", &c.message.content) + .unwrap(); choice_dict.set_item("message", message_dict).unwrap(); - choice_dict.set_item("finish_reason", &c.finish_reason).unwrap(); + choice_dict + .set_item("finish_reason", &c.finish_reason) + .unwrap(); choice_dict.to_object(py) }), );
