Struct PrimOp 

pub struct PrimOp { /* private fields */ }

Implementations

impl PrimOp

pub fn new<const N: usize>( eval_state: &mut EvalState, meta: PrimOpMeta<'_, N>, f: Box<dyn Fn(&mut EvalState, &[Value; N]) -> Result<Value>>, ) -> Result<PrimOp>

Create a new primop with the given metadata and implementation.

When f returns an Err, the error is propagated to the Nix evaluator. To return a recoverable error, include it in the error chain (e.g. Err(RecoverableError::new("...").into())).

Trait Implementations
