}Expand description
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 |
|---|---|
data | Directly pass in the value this field should contain |
data_ref_builder | Use a function or closure: (data: &_) -> Result<data_ref: _, Error_> |

sourcepub(crate) async fn try_build(self) -> Result<DataAndRef, Error_>
pub(crate) async fn try_build(self) -> Result<DataAndRef, Error_>
Calls DataAndRef::try_new() using the provided values. This is preferrable over calling try_new() directly for the reasons listed above.
sourcepub(crate) async fn try_build_or_recover(
self
) -> Result<DataAndRef, (Error_, Heads)>
pub(crate) async fn try_build_or_recover(
self
) -> Result<DataAndRef, (Error_, Heads)>
Calls DataAndRef::try_new_or_recover() using the provided values. This is preferrable over calling try_new_or_recover() directly for the reasons listed above.
