Struct Iterator 

pub struct Iterator<T: Storable> { /* private fields */ }

Iterator over collection items

Provides methods to iterate through all items in a collection.

Implementations

impl<T: Storable> Iterator<T>

pub fn collect_all(&self) -> Result<Vec<T>>

Collect all items into a vector

Warning

This will load all items into memory. Use with caution on large collections.

pub fn for_each<F>(&self, f: F) -> Result<IterationStatus>

where F: FnMut(T) -> bool,

Iterate and apply a function to each item

This is more memory-efficient than collect_all() for large datasets.

Arguments

• f - Function to apply to each item. Return false to stop iteration early.

Returns

Returns Ok(IterationStatus) where the status indicates whether iteration completed or was stopped early by the callback.

pub fn count(&self) -> Result<usize>

Count the total number of items
