pub struct ResultSifter<T> { /* private fields */ }

Helper struct used to process an iterator of Result<Vec<T>, syn::Error>, combining errors into one along the way.

Implementations

impl<T> ResultSifter<T>

pub fn sift(&mut self, result: Result<T, Error>)

Sift the given result, combining errors if necessary.

pub fn fold(sifter: Self, result: Result<T, Error>) -> Self

Associated method that provides a convenient implementation for Iterator::fold.

pub fn finish(self) -> Result<Vec<T>, Error>

Complete the sifting process and return the final result.
