Trait sanakirja::Storable[−][src]

pub trait Storable: Debug {
    type PageReferences: Iterator;
    pub fn page_references(&self) -> Self::PageReferences;

    pub fn compare<T>(&self, _txn: &T, _b: &Self) -> Ordering
    where
        T: LoadPage,
    { ... }
}

Types that can be stored on disk. This trait may be used in conjunction with Sized in order to determine the on-disk size, or with UnsizedStorable when special arrangements are needed.

Associated Types

`type PageReferences: Iterator`[src]

An iterator over the offsets to pages contained in this value. Only values from this crate can generate non-empty iterators, but combined values (like tuples) must chain the iterators returned by method page_offsets.

Required methods

`pub fn page_references(&self) -> Self::PageReferences`[src]

If this value is an offset to another page at offset offset, return Some(offset). Return None else.

Provided methods

`pub fn compare<T>(&self, _txn: &T, _b: &Self) -> Ordering where T: LoadPage,` [src]

This is required for B trees, not necessarily for other structures. The default implementation panics.
