Struct DefaultMutation 

pub struct DefaultMutation {
    pub target_struct: Option<String>,
    pub use_derive: bool,
}

Add Default implementation to structs

This mutation adds #[derive(Default)] or generates impl Default for structs that don’t have it.

Example

use ryo_mutations::idiom::DefaultMutation;

let mutation = DefaultMutation::new();
let result = mutation.apply(&mut file);

Fields

target_struct: Option<String>

Only apply to specific struct

use_derive: bool

Use #[derive(Default)] instead of impl (default: true)

Implementations

impl DefaultMutation

pub fn new() -> Self

pub fn for_struct(self, name: impl Into<String>) -> Self

Only apply to a specific struct

pub fn with_derive(self, use_derive: bool) -> Self

Use #[derive(Default)] (true) or impl Default (false)
