Struct VariableSchema 

pub struct VariableSchema {
    pub variables: HashMap<String, VariableInfo>,
    pub frame_size: usize,
}

Schema describing the structure and metadata of telemetry variables.

Fields

variables: HashMap<String, VariableInfo>

Map of variable names to their metadata (provides O(1) lookup)

frame_size: usize

Total size of a telemetry frame in bytes

Implementations

impl VariableSchema

pub fn new( variables: HashMap<String, VariableInfo>, frame_size: usize, ) -> Result<VariableSchema, TelemetryError>

Create a new VariableSchema with validation.

pub fn validate(&self) -> Result<(), TelemetryError>

Validate the schema for consistency.

pub fn get_variable(&self, name: &str) -> Option<&VariableInfo>

Get variable info by name (O(1) lookup).

pub fn has_variable(&self, name: &str) -> bool

Check if a variable exists.

pub fn variable_count(&self) -> usize

Get the number of variables.

Trait Implementations

impl Clone for VariableSchema

fn clone(&self) -> VariableSchema

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VariableSchema

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VariableSchema

fn deserialize<__D>( __deserializer: __D, ) -> Result<VariableSchema, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Flatten for VariableSchema

impl NamedType for VariableSchema

fn sid() -> SpectaID

fn named_data_type( type_map: &mut TypeCollection, generics: &[DataType], ) -> NamedDataType

this is equivalent to Type::inline but returns a NamedDataType instead.

fn definition_named_data_type(type_map: &mut TypeCollection) -> NamedDataType

this is equivalent to [Type::definition] but returns a NamedDataType instead.

impl Serialize for VariableSchema

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Type for VariableSchema

fn inline(type_map: &mut TypeCollection, generics: Generics<'_>) -> DataType

Returns the definition of a type using the provided generics.

fn reference(type_map: &mut TypeCollection, generics: &[DataType]) -> Reference

Generates a datatype corresponding to a reference to this type, as determined by its category. Getting a reference to a type implies that it should belong in the type map (since it has to be referenced from somewhere), so the output of definition will be put into the type map.
