//! Error types for FPGA softener implementations.
//!
//! This module defines error types specific to vendor-specific softener implementations
//! (like Xilinx DFX Manager). These errors are converted to the main [`crate::error::FpgadError`] type
//! for propagation through the daemon's DBus interfaces.
//!
//! # Error Types
//!
//! - [`FpgadSoftenerError`] - Errors from vendor-specific softener operations
//!
//! # Error Handling
//!
//! Softener errors implement conversion traits to both `fdo::Error` (for DBus responses)
//! and `FpgadError` (for internal error handling). All errors are logged when converted.

/// Errors specific to FPGA softener implementations.
///
/// This enum represents errors that occur in vendor-specific softener code,
/// such as failures in communication with external tools or daemons (e.g., dfx-mgr-client).
#[derive(Debug, thiserror::Error)]
pub enum FpgadSoftenerError {
    /// Error from Xilinx DFX Manager operations.
    ///
    /// This variant represents failures when calling dfx-mgr-client or when
    /// dfx-mgrd is not available or returns an error. The string contains
    /// detailed error information from the dfx-mgr tooling.
    #[error("FpgadSoftenerError::DfxMgr: {0}")]
    DfxMgr(std::io::Error),
