Struct HoldTable 

pub struct HoldTable { /* private fields */ }

Named-slot value buffer with bounded distinct-slot count.

Implementations

impl HoldTable

pub const DEFAULT_MAX_SLOTS: usize = 1024

Default cap on distinct slot names. 1024 covers any reasonable user workload while bounding the worst-case memory footprint of an unknown-key flood.

pub fn new() -> Self

Construct a fresh empty table with the default cap.

pub fn with_max_slots(max_slots: usize) -> Self

Construct with a custom max distinct-slot cap.

pub fn stash(&mut self, slot: &str, bytes: Vec<u8>)

Stash bytes into the named slot. Overwrites any previous value (existing slot names ALWAYS replace cleanly). New slot names that would exceed the table’s configured cap are dropped and the drop counter ticks.

pub fn flush(&mut self, slot: &str) -> Option<Vec<u8>>

Take the stashed value from the named slot, if present.

pub fn drops(&self) -> u64

Cumulative drop count for new-slot-on-full attempts.
