Since both traits are defined in `::mingling::__private`, this change has **no impact on the public API** — end users interact with `StructuralData` only through auto-generated derive macros and `pack_structural!`/`group_structural!` macros, which are automatically updated. Only users with manual `impl StructuralData` blocks (an advanced/rare case) need to update their code. +7. **[`core`]** **`RenderResult` now derives `Clone` and `Eq` in addition to `Default`, `Debug`, and `PartialEq`.** Added `Clone` and `Eq` derive macros to the `RenderResult` struct in `mingling_core/src/renderer/render_result.rs`. These additions enable `RenderResult` values to be explicitly cloned and support equality comparisons that are both reflexive and transitive. + + - **`Clone`** — Allows a `RenderResult` to be duplicated via `.clone()`, which is useful for scenarios where the same render output needs to be reused or stored in multiple locations. + - **`Eq`** — Enables `RenderResult` to be used in contexts that require full equivalence (e.g., `assert_eq!` with `Eq` bounds, `HashMap`/`HashSet` keys when combined with `Hash`). + + _No migration is required — these are purely additive derives that expand the type's capabilities without affecting existing behavior._ + #### Features: 1. **[`core`]** Added `RenderResult::new()` method for creating a new `RenderResult` with default values (empty text and exit code 0). This provides a more explicit and discoverable constructor compared to `RenderResult::default()`, making it clearer when a fresh result is being created for use with `write!`/`writeln!`. diff --git a/mingling_core/src/renderer/render_result.rs b/mingling_core/src/renderer/render_result.rs index c38522a..8757376 100644 --- a/mingling_core/src/renderer/render_result.rs +++ b/mingling_core/src/renderer/render_result.rs @@ -6,7 +6,7 @@ use std::{ use crate::RenderResultMode::{Stderr, Stdout}; /// Render result, containing the rendered text content. -#[derive(Default, Debug, PartialEq)] +#[derive(Default, Debug, Clone, PartialEq, Eq)] pub struct RenderResult { /// Whether the output should be written immediately. /// |
