Struct Definition 

pub struct Definition {
    pub path: String,
    pub value: NixValue,
    pub priority: u32,
    pub cond: Option<bool>,
}

One config definition — a value assigned to an option path, with a priority rank. Wrappers like mkDefault / mkForce / mkOverride N produce these directly with adjusted priority.

Fields

path: String

Option path this defines ("services.foo.enable").

value: NixValue

Value assigned at this path.

priority: u32

Priority level (lower = wins). See PriorityRank.

cond: Option<bool>

mkIf cond ... translates here. None = unconditional (the default and most common shape). Some(false) drops the definition before priority resolution. Some(true) keeps it (equivalent to None).

Nested mkIf wrappers collapse to a single AND-combined bool at translation time — this surface stays Boolean.

Trait Implementations

impl Clone for Definition

fn clone(&self) -> Definition

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Definition

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
