Enum msr_core::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.
