Module error

Expand description

Unified error types for the perfgate ecosystem.

This module provides a single, comprehensive error type that unifies all error variants from across the perfgate crates. It enables seamless error propagation and conversion between different error types.

Part of the perfgate workspace.

§Error Categories

The PerfgateError enum is organized into categories:

Validation: Bench name validation, config validation
Stats: Statistical computation errors (no samples)
Adapter: Process execution, I/O, platform-specific errors
Config: Configuration parsing and validation errors
IO: File system and network I/O errors
Paired: Paired benchmark errors
Auth: Authentication and authorization errors
Parse: JSON and TOML deserialization errors

§Example

use perfgate_types::error::{PerfgateError, ValidationError};

fn validate_name(name: &str) -> Result<(), PerfgateError> {
    if name.is_empty() {
        return Err(ValidationError::Empty.into());
    }
    Ok(())
}

let err = validate_name("").unwrap_err();
assert!(matches!(err, PerfgateError::Validation(ValidationError::Empty)));
