Trait MessagesExt 

pub trait MessagesExt {
    type Output: MultiAccumulator + FromIterator<(String, ValueAccumulator)>;

    // Required method
    fn accumulate_trailers<'a, I, J>(self, specs: I) -> Self::Output
       where I: IntoIterator<Item = J>,
             J: Borrow<TrailerSpec<'a>>;
}

Messages iterator extension trait

This trait provides some convenience functionality for iterators over Messages which does not need to be part of Messages or another iterator.

Required Associated Types

type Output: MultiAccumulator + FromIterator<(String, ValueAccumulator)>

Required Methods

fn accumulate_trailers<'a, I, J>(self, specs: I) -> Self::Output

where I: IntoIterator<Item = J>, J: Borrow<TrailerSpec<'a>>,

Accumulate trailers according to the specification provided

This function accumulates all specified trailers from the messages returned by the iterator.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl<'a, I> MessagesExt for I

where I: Iterator<Item = Commit<'a>>,

type Output = HashMap<String, ValueAccumulator>
