Struct OwnedValueLease

Source

pub struct OwnedValueLease { /* private fields */ }

Expand description

An owned lease over one value in an immutable packed leaf.

The byte slice remains valid for the lifetime of this object even if the shared node cache evicts the leaf. Native bindings use this as the owner behind callback-scoped zero-copy value views.

impl OwnedValueLease

Source

pub fn as_bytes(&self) -> Result<&[u8], Error>

Source

pub fn retained_bytes(&self) -> usize
