Timer

macro Timer(context: TokenTreeMacroContext) -> StatementSyntax

Namespace: Raven.Macros
Assembly: Raven.Macros.dll
Source file: Timer.rvn

Measures an ordinary Raven block body with System.Diagnostics.Stopwatch and writes the elapsed duration. An optional message template uses {time} for the elapsed duration while retaining Raven's ordinary $name and ${expression} interpolation.

The invocation occupies statement position. Release builds report a warning so accidental instrumentation is visible without preventing compilation.

Example

import Raven.Macros.*

timer! {
    let index = LoadIndex()
    Rebuild(index)
    Save(index)
}

let operation = "Index rebuild"
timer! "$operation succeeded in {time}" {
    RebuildIndex()
}
