Implementations

impl<T: 'static> ReadAccountMapEntry<T>

pub fn new(
    owned_entry: Arc<AccountMapEntryInner<T>>,
    slot_list_guard_builder: impl for<'this> FnOnce(&'this <Arc<AccountMapEntryInner<T>> as Deref>::Target) -> RwLockReadGuard<'this, SlotList<T>>
) -> Self

Constructs a new instance of this self-referential struct. (See also ReadAccountMapEntryBuilder::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
owned_entry	Directly pass in the value this field should contain
slot_list_guard_builder	Use a function or closure: (owned_entry: &_) -> slot_list_guard: _

pub fn try_new<Error_>(
    owned_entry: Arc<AccountMapEntryInner<T>>,
    slot_list_guard_builder: impl for<'this> FnOnce(&'this <Arc<AccountMapEntryInner<T>> as Deref>::Target) -> Result<RwLockReadGuard<'this, SlotList<T>>, Error_>
) -> Result<Self, Error_>

(See also ReadAccountMapEntryTryBuilder::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:

Argument	Suggested Use
owned_entry	Directly pass in the value this field should contain
slot_list_guard_builder	Use a function or closure: (owned_entry: &_) -> Result<slot_list_guard: _, Error_>

pub fn try_new_or_recover<Error_>(
    owned_entry: Arc<AccountMapEntryInner<T>>,
    slot_list_guard_builder: impl for<'this> FnOnce(&'this <Arc<AccountMapEntryInner<T>> as Deref>::Target) -> Result<RwLockReadGuard<'this, SlotList<T>>, Error_>
) -> Result<Self, (Error_, Heads<T>)>

(See also ReadAccountMapEntryTryBuilder::try_build_or_recover().) Like try_new, but all head fields are returned in the case of an error. The arguments are as follows:

Argument	Suggested Use
owned_entry	Directly pass in the value this field should contain
slot_list_guard_builder	Use a function or closure: (owned_entry: &_) -> Result<slot_list_guard: _, Error_>

pub fn with_owned_entry_contents<'outer_borrow, ReturnType>(
    &'outer_borrow self,
    user: impl for<'this> FnOnce(&'outer_borrow <Arc<AccountMapEntryInner<T>> as Deref>::Target) -> ReturnType
) -> ReturnType

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

pub fn with_slot_list_guard<'outer_borrow, ReturnType>(
    &'outer_borrow self,
    user: impl for<'this> FnOnce(&'outer_borrow RwLockReadGuard<'this, SlotList<T>>) -> ReturnType
) -> ReturnType

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

pub fn with_slot_list_guard_mut<'outer_borrow, ReturnType>(
    &'outer_borrow mut self,
    user: impl for<'this> FnOnce(&'outer_borrow mut RwLockReadGuard<'this, SlotList<T>>) -> ReturnType
) -> ReturnType

Provides a mutable reference to slot_list_guard. This method was generated because slot_list_guard is a tail field.

pub fn with<'outer_borrow, ReturnType>(
    &'outer_borrow self,
    user: impl for<'this> FnOnce(BorrowedFields<'outer_borrow, 'this, T>) -> ReturnType
) -> ReturnType

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

pub fn with_mut<'outer_borrow, ReturnType>(
    &'outer_borrow mut self,
    user: impl for<'this> FnOnce(BorrowedMutFields<'outer_borrow, 'this, T>) -> ReturnType
) -> ReturnType

This method provides mutable references to all tail fields.

pub fn into_heads(self) -> Heads<T>

This function drops all internally referencing fields and returns only the head fields of this struct.
