Struct Memo 

#[non_exhaustive]
pub struct Memo { /* private fields */ }

A collection of memo payloads that can be deserialized into typed values.

Implementations

impl Memo

pub fn from_raw( raw: Option<Memo>, payload_converter: PayloadConverter, context: SerializationContextData, ) -> Memo

Construct a memo with the payload converter and serialization context associated with its source.

pub fn get<T>(&self, key: &str) -> Result<Option<T>, PayloadConversionError>

where T: TemporalDeserializable + 'static,

Decode a memo value as T, returning None when the key is absent.

pub fn contains_key(&self, key: &str) -> bool

Returns whether the memo contains key.

pub fn len(&self) -> usize

Returns the number of memo entries.

pub fn is_empty(&self) -> bool

Returns whether the memo has no entries.

pub fn keys(&self) -> impl Iterator<Item = &str>

Iterates over memo keys in lexicographic order.

pub fn raw_value(&self, key: &str) -> Option<&Payload>

Returns the underlying payload without applying payload conversion.

pub fn raw(&self) -> &Memo

Access the underlying memo protobuf.

pub fn into_raw(self) -> Memo

Consume this wrapper and return the underlying memo protobuf.

Trait Implementations
