Struct ouroboros_examples::Chain [−][src]
pub struct Chain { /* fields omitted */ }
Implementations
Constructs a new instance of this self-referential struct. (See also ChainBuilder::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 |
---|---|
a | Directly pass in the value this field should contain |
b_builder | Use a function or closure: (a: &_) -> b: _ |
c_builder | Use a function or closure: (b: &_) -> c: _ |

(See also ChainTryBuilder::try_build()

, 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 a mutable reference to c
. This method was generated because c
is a tail field. No borrow_c_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>(

) -> ReturnType
This method provides immutable references to all tail and immutably borrowed fields.
pub(crate) fn with_mut<'outer_borrow, ReturnType>(
&'outer_borrow mut self,
user: impl for<'this> FnOnce(BorrowedMutFields<'outer_borrow, 'this>) -> ReturnType

pub(crate) fn with_mut<'outer_borrow, ReturnType>(
&'outer_borrow mut self,
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.
