Enum Value

pub enum Value {
    Scalar(ScalarValue),
    Duration(Duration),
    String(String),
    Bytes(Vec<u8>),
}

A value representation within a MSR system.

TODO: Split into a separate type for simple, copyable values and an enclosing type that includes the complex, non-real-time-safe values?

Variants

Scalar(ScalarValue)

Scalar value (real-time safe)

This variant can safely be used in real-time contexts.

Duration(Duration)

Duration, e.g. a timeout

This variant can safely be used in real-time contexts.

String(String)

Variable-size text data

This variant must not be used in real-time contexts.

Bytes(Vec<u8>)

Variable-size binary data

This variant must not be used in real-time contexts.

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl From<Duration> for Value

fn from(from: Duration) -> Value

Converts to this type from the input type.

impl<S> From<S> for Value

where S: Into<ScalarValue>,

fn from(from: S) -> Self

Converts to this type from the input type.

impl From<String> for Value

fn from(from: String) -> Value

Converts to this type from the input type.

impl From<Vec<u8>> for Value

fn from(from: Vec<u8>) -> Value

Converts to this type from the input type.

impl PartialEq for Value

fn eq(&self, other: &Value) -> 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 ToValueType for Value

fn to_value_type(&self) -> ValueType

impl StructuralPartialEq for Value
