Struct ProfileInterval 

pub struct ProfileInterval { /* private fields */ }

A profiling interval that logs when created and dropped.

ProfileInterval logs a BEGIN message when created and an END message with elapsed duration when dropped. Each interval has a unique ID to correlate BEGIN/END pairs, which is especially useful when profiling nested operations.

Unlike PerfwarnInterval, this type:

• Always logs (no threshold)
• Logs both BEGIN and END messages
• Does not contribute to task statistics
• Is intended for temporary profiling that should be removed before committing

Usage

This type is typically not created directly. Instead, use the profile_begin! macro which properly sets up the interval with source location information.

Example

logwise::declare_logging_domain!();
// Using profile_begin! for manual interval management
let interval = logwise::profile_begin!("database_query");
perform_operation();
// BEGIN logged when created, END logged when dropped
drop(interval);

Log Output

The interval produces log messages like:

PROFILE: BEGIN [id=1] src/main.rs:10:5 [0ns] database_query
PROFILE: END [id=1] [elapsed: 150µs] database_query

Implementations

impl ProfileInterval

pub fn new(id: u64, label: &'static str, time: Instant) -> Self

Creates a new profile interval.

Do not use this manually. Instead use the profile_begin! macro which properly captures source location information.

Arguments

• id - Unique identifier for correlating BEGIN/END messages
• label - A static string identifying this interval in log messages
• time - The start time of the interval

pub fn id(&self) -> u64

Returns the unique ID of this profile interval.

Trait Implementations
