Struct ouroboros_examples::ouroboros_impl_with_const_param::WithConstParamAsyncTryBuilder

pub struct WithConstParamAsyncTryBuilder<T: 'static, const REV: bool, DrefBuilder_: for<'this> FnOnce(&'this RefCell<T>) -> Pin<Box<dyn Future<Output = Result<Option<Box<Ext<'this, T, REV>>>, Error_>> + 'this>>, Error_> {
    pub data: RefCell<T>,
    pub dref_builder: DrefBuilder_,
}

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 making 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
data	Directly pass in the value this field should contain
dref_builder	Use a function or closure: (data: &_) -> Result<dref: _, Error_>

Fields

data: RefCell<T>

dref_builder: DrefBuilder_

Implementations

impl<T: 'static, const REV: bool, DrefBuilder_: for<'this> FnOnce(&'this RefCell<T>) -> Pin<Box<dyn Future<Output = Result<Option<Box<Ext<'this, T, REV>>>, Error_>> + 'this>>, Error_> WithConstParamAsyncTryBuilder<T, REV, DrefBuilder_, Error_>

pub async fn try_build(self) -> Result<WithConstParam<T, REV>, Error_>

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

pub async fn try_build_or_recover( self ) -> Result<WithConstParam<T, REV>, (Error_, Heads<T, REV>)>

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