# Shisho Policy Rust SDK 

This is a helper crate for Shisho Cloud workflows to write custom policies. 

This is the core library to write custom policies.
- `decision` includes the structs of `output data`(=`decsion` results).
- `gqlgen` includes the functionalities of converting from `geraphql` schema and queries. The original code comes from [`graphql-client/graphql_client_codegen`](https://github.com/graphql-rust/graphql-client/tree/main/graphql_client_codegen)
- `schema` includes the string of `datasource` graphql query. The schema is generated by the codegen.

## Required crate

This required the helper crate, [`shisho-gql-derive`](https://crates.io/crates/shisho-gql-derive)

## Example usage

```
use shisho_gql_derive::*;
pub use shisho_policy_sdk::decision::data_entry::*;
pub use shisho_policy_sdk::decision::github::organization::org_owners::*;
pub use shisho_policy_sdk::decision::*;

use self::input::InputGithubOrganizations;

#[allow(dead_code)]
#[derive(ShishoGraphQLQuery)]
#[shisho_graphql(
    query_path = "src/policies/organization/org_owners/query.graphql",
    response_derives = "Debug, PartialEq"
)]
pub struct Input;

pub fn decisions(input: input::InputData) -> Vec<Decision<OrgOwnersEntryData>> {
    input
        .github
        .organizations
        .into_iter()
        .map(|o: InputGithubOrganizations| decide_on_each_org(o))
        .collect()
}

pub fn decide_on_each_org(o: InputGithubOrganizations) -> Decision<OrgOwnersEntryData> {
    ...
}
```
