Trait RecordAttribute 

pub trait RecordAttribute {
    const FIELD_NAMES: &'static [&'static str];
    const PLURALIZE_FIELD_NAMES: bool = false;

    // Required method
    fn record_attribute(&self) -> impl Value + '_;
}

Converts a value into its canonical tracing attribute representation.

Values passed to the Miden tracing span and event macros must implement this trait. Implementations decide the allowed scalar field names, the attribute’s primitive type, and its formatting, allowing tracing macros to use one name and representation consistently at every recording site. Collection implementations derive their field names by appending s to these scalar names.

Required Associated Constants

const FIELD_NAMES: &'static [&'static str]

Scalar field names associated with this value’s type.

Provided Associated Constants

const PLURALIZE_FIELD_NAMES: bool = false

Whether the final component of each field name must have an s suffix.

Required Methods

fn record_attribute(&self) -> impl Value + '_

Returns the value that is passed to tracing.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

impl RecordAttribute for Duration

Durations are recorded as whole milliseconds in a u64, saturating at u64::MAX.

Every allowed field name ends with ms so the recorded unit is visible on the query side.
