Struct EitherTraversal 

pub struct EitherTraversal<A, B> {
    pub successes: Vec<B>,
    pub error: Option<A>,
}

A traversal context for applying an Either-returning function across a collection.

Fields

successes: Vec<B>

The accumulated successful (Left in OxiEither) results so far.

error: Option<A>

The first error encountered, if any.

Implementations

impl<A, B> EitherTraversal<A, B>

pub fn new() -> Self

Create a new, empty traversal context.

pub fn step(&mut self, value: OxiEither<B, A>)

Step the traversal with a new Either value. Once an error is set, subsequent values are ignored.

pub fn finish(self) -> OxiEither<Vec<B>, A>

Finalise the traversal, consuming self. Returns Left(successes) if no error occurred, or Right(error).

pub fn has_error(&self) -> bool

Returns true if traversal ended with an error.

pub fn success_count(&self) -> usize

Returns the count of accumulated successes.

Trait Implementations

impl<A, B> Default for EitherTraversal<A, B>

fn default() -> Self

Returns the “default value” for a type.
