Struct ouroboros_examples::ouroboros_impl_documentation_example::DocumentationExampleAsyncTryBuilder [−][src]
pub(crate) struct DocumentationExampleAsyncTryBuilder<IntReferenceBuilder_: for<'this> FnOnce(&'this i32) -> Pin<Box<dyn Future<Output = Result<&'this i32, Error_>> + 'this>>, FloatReferenceBuilder_: for<'this> FnOnce(&'this mut f32) -> Pin<Box<dyn Future<Output = Result<&'this mut f32, Error_>> + 'this>>, Error_> { pub(crate) int_data: i32, pub(crate) float_data: f32, pub(crate) int_reference_builder: IntReferenceBuilder_, pub(crate) float_reference_builder: FloatReferenceBuilder_, }
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 |
---|---|
int_data | Directly pass in the value this field should contain |
float_data | Directly pass in the value this field should contain |
int_reference_builder | Use a function or closure: (int_data: &_) -> Result<int_reference: _, Error_> |
float_reference_builder | Use a function or closure: (float_data: &mut _) -> Result<float_reference: _, Error_> |
Fields
int_data: i32
float_data: f32
int_reference_builder: IntReferenceBuilder_
float_reference_builder: FloatReferenceBuilder_
Implementations
impl<IntReferenceBuilder_: for<'this> FnOnce(&'this i32) -> Pin<Box<dyn Future<Output = Result<&'this i32, Error_>> + 'this>>, FloatReferenceBuilder_: for<'this> FnOnce(&'this mut f32) -> Pin<Box<dyn Future<Output = Result<&'this mut f32, Error_>> + 'this>>, Error_> DocumentationExampleAsyncTryBuilder<IntReferenceBuilder_, FloatReferenceBuilder_, Error_>
impl<IntReferenceBuilder_: for<'this> FnOnce(&'this i32) -> Pin<Box<dyn Future<Output = Result<&'this i32, Error_>> + 'this>>, FloatReferenceBuilder_: for<'this> FnOnce(&'this mut f32) -> Pin<Box<dyn Future<Output = Result<&'this mut f32, Error_>> + 'this>>, Error_> DocumentationExampleAsyncTryBuilder<IntReferenceBuilder_, FloatReferenceBuilder_, Error_>
Calls DocumentationExample::try_new()
using the provided values. This is preferrable over calling try_new()
directly for the reasons listed above.
pub(crate) async fn try_build_or_recover(
self
) -> Result<DocumentationExample, (Error_, Heads)>
pub(crate) async fn try_build_or_recover(
self
) -> Result<DocumentationExample, (Error_, Heads)>
Calls DocumentationExample::try_new_or_recover()
using the provided values. This is preferrable over calling try_new_or_recover()
directly for the reasons listed above.
