pyproject.toml parser in Rust


GitHub Actions

pyproject.toml parser in Rust.


Add it to your Cargo.toml:

pyproject-toml = "0.3"

then you are good to go. If you are using Rust 2015 you have to add extern crate pyproject_toml to your crate root as well.

Extended parsing

If you want to add additional fields parsing, you can do it with serde's flatten feature and implement the Deref trait, for example:

use serde::{Deserialize, Serialize};

#[derive(Serialize, Deserialize, Debug, Clone)]
pub struct PyProjectToml {
    inner: pyproject_toml::PyProjectToml,
    tool: Option<Tool>,

#[derive(Serialize, Deserialize, Debug, Clone)]
#[serde(rename_all = "kebab-case")]
pub struct Tool {
    maturin: Option<ToolMaturin>,

#[derive(Serialize, Deserialize, Debug, Clone)]
#[serde(rename_all = "kebab-case")]
pub struct ToolMaturin {
    sdist_include: Option<Vec<String>>,

impl std::ops::Deref for PyProjectToml {
    type Target = pyproject_toml::PyProjectToml;

    fn deref(&self) -> &Self::Target {

impl PyProjectToml {
    pub fn new(content: &str) -> Result<Self, toml::de::Error> {
