Struct DataContent 

#[non_exhaustive]
pub struct DataContent {
    pub key: String,
    pub delayed: Option<bool>,
    pub asset_main_type: Option<AssetMainType>,
    pub asset_sub_type: Option<AssetSubType>,
    pub cusip: Option<String>,
    pub fields: HashMap<String, Value>,
}

One item of a data frame as the streamer sends it: the subscription key, the service’s envelope keys, and the numbered fields.

Decode into named, typed fields with StreamService::decode or a payload’s from_content (for example LevelOneEquity::from_content).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

key: String

delayed: Option<bool>

asset_main_type: Option<AssetMainType>

asset_sub_type: Option<AssetSubType>

cusip: Option<String>

fields: HashMap<String, Value>

The numbered fields ("1", "2", …) plus any other key the service sends, such as seq on chart and account-activity items.

Implementations

impl DataContent

pub fn named_fields(&self, table: &[Field]) -> Map<String, Value>

The numbered fields renamed per table (see StreamService::fields). Numbers the table does not list, and non-numeric keys such as seq, pass through unchanged.

pub fn to_named_value(&self, table: &[Field]) -> Value

The whole item as one JSON object: the envelope (key, delayed, assetMainType, …) plus named_fields. This is the shape the typed payloads deserialize from.

pub fn into_named_value(self, table: &[Field]) -> Value

to_named_value without copying: for consumers that own the item and do not need it afterwards.

Trait Implementations

impl Clone for DataContent

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataContent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DataContent

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for DataContent

Available on crate feature schemars only.

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Serialize for DataContent

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
