Struct ClientAttTable 

pub struct ClientAttTable { /* private fields */ }

A compact, fixed-size map of client-specific attribute values (e.g. CCCDs).

Entries are stored in a flat byte buffer with a sorted index for binary-search lookups. CLIENT_ATT_TABLE_SIZE determines the total storage available for both the index and values.

Implementations

impl ClientAttTable

pub const fn builder() -> ClientAttTableBuilder

Creates a new ClientAttTableBuilder for constructing a ClientAttTable.

pub const fn view(&self) -> ClientAttTableView<'_>

Get a read-only view of the table

pub fn get(&self, key: u16) -> Option<&[u8]>

Returns a reference to the value associated with the given attribute handle, or None if not found.

pub fn write( &mut self, key: u16, offset: usize, data: &[u8], ) -> Result<(), AttErrorCode>

Writes data to key starting at offset.

pub fn set_values(&mut self, src: &ClientAttTableView<'_>)

Copies values from src into this map for all matching keys.

Keys present in this map but not in src are zeroed. If value sizes differ, only the smaller length is copied and the remainder is zeroed.

pub fn clear(&mut self)

Zeros all values in the map, leaving the index structure intact.

pub fn raw(&self) -> &[u8]

Returns the raw byte representation of the map, suitable for serialization or storage.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ClientAttTable

fn fmt(&self, f: &mut Formatter<'_>) -> Result
