Struct email::email::message::ouroboros_impl_message::MessageAsyncSendTryBuilder

pub(super) struct MessageAsyncSendTryBuilder<'a, ParsedBuilder_: for<'this> FnOnce(&'this mut RawMessage<'a>) -> Pin<Box<dyn Future<Output = Result<Option<Message<'this>>, Error_>> + Send + 'this>>, Error_> {
    pub(super) raw: RawMessage<'a>,
    pub(super) parsed_builder: ParsedBuilder_,
}

A more verbose but stable way to construct self-referencing structs. It is comparable to using StructName { field1: value1, field2: value2 } rather than StructName::new(value1, value2). This has the dual benefit of makin your code both easier to refactor and more readable. Call try_build() or try_build_or_recover() to construct the actual struct. The fields of this struct should be used as follows:

Field	Suggested Use
raw	Directly pass in the value this field should contain
parsed_builder	Use a function or closure: (raw: &mut _) -> Result<parsed: _, Error_>

Fields

raw: RawMessage<'a>

parsed_builder: ParsedBuilder_

Implementations

impl<'a, ParsedBuilder_: for<'this> FnOnce(&'this mut RawMessage<'a>) -> Pin<Box<dyn Future<Output = Result<Option<Message<'this>>, Error_>> + Send + 'this>>, Error_> MessageAsyncSendTryBuilder<'a, ParsedBuilder_, Error_>

pub(super) async fn try_build(self) -> Result<Message<'a>, Error_>

Calls Message::try_new() using the provided values. This is preferrable over calling try_new() directly for the reasons listed above.

pub(super) async fn try_build_or_recover( self ) -> Result<Message<'a>, (Error_, Heads<'a>)>

Calls Message::try_new_or_recover() using the provided values. This is preferrable over calling try_new_or_recover() directly for the reasons listed above.
