Struct Eh 

pub struct Eh<L: Loss> { /* private fields */ }

Terni-functor composition context.

Accumulates loss across a sequence of Imperfect operations, converting each to Result for use with ?.

Call .finish() to wrap the final value with accumulated loss.

Implementations

impl<L: Loss> Eh<L>

pub fn new() -> Self

Create a new composition context with zero accumulated loss.

pub fn eh<T, E>(&mut self, imp: Imperfect<T, E, L>) -> Result<T, E>

Extract value from Imperfect, accumulating loss. Returns Result<T, E> for use with ?.

pub fn imp<T, E>(&mut self, imp: Imperfect<T, E, L>) -> Result<T, E>

Alias for eh. The name. For the mischievous ones.

pub fn tri<T, E>(&mut self, imp: Imperfect<T, E, L>) -> Result<T, E>

Alias for eh.

pub fn finish<T, E>(self, value: T) -> Imperfect<T, E, L>

Wrap a final value with accumulated loss. Success if no loss accumulated. Partial if any did.

pub fn loss(&self) -> Option<&L>

Inspect accumulated loss without consuming the context.

Trait Implementations

impl<L: Loss> Default for Eh<L>

fn default() -> Self

Returns the “default value” for a type.
