Trait mz_compute::render::errors::MaybeValidatingRow

pub(super) trait MaybeValidatingRow<T, E>: ExchangeData + Columnation + Hash {
    // Required methods
    fn ok(t: T) -> Self;
    fn into_error() -> Option<fn(_: E) -> Self>;
}

Used to make possibly-validating code generic: think of this as a kind of MaybeResult, specialized for use in compute. Validation code will only run when the error constructor is Some.

Required Methods

fn ok(t: T) -> Self

fn into_error() -> Option<fn(_: E) -> Self>

Object Safety

This trait is not object safe.
