ruff_notebook 0.0.10

//! The JSON schema of a Jupyter Notebook, entrypoint is [`RawNotebook`]
//!
//! Generated by <https://app.quicktype.io/> from
//! <https://github.com/jupyter/nbformat/blob/16b53251aabf472ad9406ddb1f78b0421c014eeb/nbformat/v4/nbformat.v4.schema.json>
//! Jupyter Notebook v4.5 JSON schema.
//!
//! The following changes were made to the generated version:
//! * Only keep the required structs and enums.
//! * `Cell::id` is optional because it wasn't required <v4.5
//! * `#[serde(deny_unknown_fields)]` was added where the schema had
//!   `"additionalProperties": false`
//! * `#[serde(flatten)] pub other: BTreeMap<String, Value>` for
//!   `"additionalProperties": true` as preparation for round-trip support.
//! * `#[serde(skip_serializing_if = "Option::is_none")]` was added to optional
//!   fields where `null` values should not be serialized.
//! * `Cell::execution_count` is a required property only for code cells, but
//!   we serialize it for all cells. This is because we can't know if a cell is
//!   a code cell or not without looking at the `cell_type` property, which
//!   would require a custom serializer.
