Struct solana_runtime::accounts_index::ouroboros_impl_read_account_map_entry::ReadAccountMapEntryAsyncTryBuilder

pub(super) struct ReadAccountMapEntryAsyncTryBuilder<T: IndexValue, SlotListGuardBuilder_: for<'this> FnOnce(&'this Arc<AccountMapEntryInner<T>>) -> Pin<Box<dyn Future<Output = Result<RwLockReadGuard<'this, SlotList<T>>, Error_>> + 'this>>, Error_> {
    pub(super) owned_entry: Arc<AccountMapEntryInner<T>>,
    pub(super) slot_list_guard_builder: SlotListGuardBuilder_,
}

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
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_>

Fields

owned_entry: Arc<AccountMapEntryInner<T>>

slot_list_guard_builder: SlotListGuardBuilder_

Implementations

impl<T: IndexValue, SlotListGuardBuilder_: for<'this> FnOnce(&'this Arc<AccountMapEntryInner<T>>) -> Pin<Box<dyn Future<Output = Result<RwLockReadGuard<'this, SlotList<T>>, Error_>> + 'this>>, Error_> ReadAccountMapEntryAsyncTryBuilder<T, SlotListGuardBuilder_, Error_>

pub(super) async fn try_build(self) -> Result<ReadAccountMapEntry<T>, Error_>

Calls ReadAccountMapEntry::try_new() using the provided values. This is preferrable over calling try_new() directly for the reasons listed above.

pub(super) async fn try_build_or_recover( self ) -> Result<ReadAccountMapEntry<T>, (Error_, Heads<T>)>

Calls ReadAccountMapEntry::try_new_or_recover() using the provided values. This is preferrable over calling try_new_or_recover() directly for the reasons listed above.
