Struct ouroboros_examples::DataAndRef [−][src]
pub struct DataAndRef { /* fields omitted */ }
Implementations
Constructs a new instance of this self-referential struct. (See also DataAndRefBuilder::build()
). Each argument is a field of the new struct. Fields that refer to other fields inside the struct are initialized using functions instead of directly passing their value. The arguments are as follows:
Argument | Suggested Use |
---|---|
data | Directly pass in the value this field should contain |
data_ref_builder | Use a function or closure: (data: &_) -> data_ref: _ |
Constructs a new instance of this self-referential struct. (See also DataAndRefAsyncBuilder::build()

data_ref_builder | Use a function or closure: (data: &_) -> data_ref: _ |
(See also DataAndRefTryBuilder::try_build()
.) Like new
, but builders for self-referencing fields can return results. If any of them fail, Err
is returned. If all of them succeed, Ok
is returned. The arguments are as follows:

Provides limited immutable access to data
. This method was generated because the contents of data
are immutably borrowed by other fields.

Provides an immutable reference to data_ref
. This method was generated because data_ref
is a tail field.

Provides a mutable reference to data_ref
. This method was generated because data_ref
is a tail field. No borrow_data_ref_mut
function was generated because Rust’s borrow checker is currently unable to guarantee that such a method would be used safely.

pub(crate) fn with<'outer_borrow, ReturnType>(

This method provides immutable references to all tail and immutably borrowed fields.

&'outer_borrow mut self,
user: impl for<'this> FnOnce(BorrowedMutFields<'outer_borrow, 'this>) -> ReturnType

pub(crate) fn with_mut<'outer_borrow, ReturnType>(

user: impl for<'this> FnOnce(BorrowedMutFields<'outer_borrow, 'this>) -> ReturnType
) -> ReturnType
This method provides mutable references to all tail fields.
This function drops all internally referencing fields and returns only the head fields of this struct.
