Struct AppDataDictionary 

pub struct AppDataDictionary { /* private fields */ }

Available on (32-bit or 64-bit) and crate feature extensions-draft-08 only.

Serializable app data dictionary in the AppDataDictionaryExtension.

This struct contains a list of ComponentData entries. Entries are in order, and there is at most one entry per ComponentId. These properties are checked upon creation, as well as upon deserialization.

Implementations

impl AppDataDictionary

pub fn new() -> Self

Initialize a new, empty AppDataDictionary.

pub fn entries(&self) -> impl Iterator<Item = &ComponentData>

Returns an iterator over the ComponentData entries, ordered by ComponentId.

pub fn to_entries(self) -> Vec<ComponentData>

Returns the data that is currently stored in the AppDataDictionary.

pub fn len(&self) -> usize

Returns the number of entries in the dictionary.

pub fn is_empty(&self) -> bool

Returns whether the dictionary has entries.

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

Get a reference to an entry in the dictionary.

pub fn insert( &mut self, component_id: ComponentId, data: Vec<u8>, ) -> Option<VLBytes>

Insert an entry into the dictionary. If an entry for this ComponentId already exists, replace the old entry and return it.

pub fn contains(&self, component_id: &ComponentId) -> bool

Returns true if the dictionary contains an entry for the specified ComponentId.

pub fn remove(&mut self, component_id: &ComponentId) -> Option<VLBytes>

Remove an entry from the dictionary by ComponentId. If this entry exists, return it.

Trait Implementations

impl Clone for AppDataDictionary

fn clone(&self) -> AppDataDictionary

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AppDataDictionary

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

Formats the value using the given formatter.

impl Default for AppDataDictionary

fn default() -> AppDataDictionary

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AppDataDictionary

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Deserialize for AppDataDictionary

fn tls_deserialize<R: Read>(bytes: &mut R) -> Result<Self, Error>

Available on crate feature std only.

Deserialize from bytes.

This function also ensures that the ComponentData entries are in order by ComponentId, and there is at most one entry per ComponentId.

fn tls_deserialize_exact(bytes: impl AsRef<[u8]>) -> Result<Self, Error>

where Self: Sized,

Available on crate feature std only.

This function deserializes the provided bytes and returns the populated struct. All bytes must be consumed.

impl DeserializeBytes for AppDataDictionary

fn tls_deserialize_bytes(bytes: &[u8]) -> Result<(Self, &[u8]), Error>

This function deserializes the bytes from the provided a &[u8] and returns the populated struct, as well as the remaining slice.

fn tls_deserialize_exact_bytes(bytes: &[u8]) -> Result<Self, Error>

where Self: Sized,

This function deserializes the provided bytes and returns the populated struct. All bytes must be consumed.

impl PartialEq for AppDataDictionary

fn eq(&self, other: &AppDataDictionary) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for AppDataDictionary

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Serialize for AppDataDictionary

fn tls_serialize<W: Write>(&self, writer: &mut W) -> Result<usize, Error>

Available on crate feature std only.

Serialize self and write it to the writer. The function returns the number of bytes written to writer.

fn tls_serialize_detached(&self) -> Result<Vec<u8>, Error>

Available on crate feature std only.

Serialize self and return it as a byte vector.

impl Size for AppDataDictionary

fn tls_serialized_len(&self) -> usize

impl Eq for AppDataDictionary
