Struct HpackDynamicTable 

pub struct HpackDynamicTable<'storage, 'entries> { /* private fields */ }

Caller-owned, allocation-free RFC 7541 dynamic-table storage.

Entries are addressed with one-based dynamic indices, where index 1 is the newest entry. The table stores only its active packed bytes and active metadata; stale caller storage is never exposed after eviction or Self::clear. This type intentionally does not combine dynamic indices with the static table.

Implementations

impl<'storage, 'entries> HpackDynamicTable<'storage, 'entries>

pub fn new( storage: &'storage mut [u8], entries: &'entries mut [HpackDynamicTableEntry], maximum_size: usize, ) -> Result<Self, HpackDynamicTableError>

Creates a table backed by caller-supplied byte and metadata storage.

The maximum is validated before either store is changed.

pub const fn capacity(&self) -> usize

Returns the maximum RFC size supported by the supplied caller storage.

pub const fn len(&self) -> usize

Returns the number of active dynamic entries.

pub const fn is_empty(&self) -> bool

Returns whether no dynamic entries are active.

pub const fn size(&self) -> usize

Returns the current RFC dynamic-table size.

pub const fn maximum_size(&self) -> usize

Returns the current configured RFC dynamic-table maximum.

pub fn get(&self, index: usize) -> Option<HpackHeaderFieldRef<'_>>

Returns the field at a one-based dynamic index, where 1 is newest.

pub fn clear(&mut self)

Removes all active entries without scrubbing inactive caller storage.

pub fn set_maximum_size( &mut self, maximum_size: usize, ) -> Result<(), HpackDynamicTableError>

Updates the configured maximum, evicting oldest entries immediately if needed.

pub fn entry_size( name: &[u8], value: &[u8], ) -> Result<usize, HpackDynamicTableError>

Calculates an RFC 7541 entry size from opaque name and value bytes.

pub fn insert( &mut self, name: &[u8], value: &[u8], ) -> Result<HpackDynamicTableInsertResult, HpackDynamicTableError>

Copies a field into the table as the newest entry, evicting oldest entries as needed.
