Enum FlashUpdate 

pub enum FlashUpdate {
    Progress {
        progress: f32,
        bytes_written: u64,
        speed_mb_s: f32,
    },
    VerifyProgress {
        phase: &'static str,
        overall: f32,
        bytes_read: u64,
        total_bytes: u64,
        speed_mb_s: f32,
    },
    Message(String),
    Completed,
    Failed(String),
}

A normalised progress event suitable for consumption by any frontend (Iced GUI, Ratatui TUI, or future integrations).

Both the GUI’s FlashProgress and the TUI’s FlashEvent wrapper types were independently duplicating this shape. By defining it once in core and converting from FlashEvent via From, each frontend only needs to bridge this into its own message/command type.

Key differences from the raw FlashEvent:

• Progress carries a normalised 0.0–1.0 write fraction (the raw event only carries raw byte counts; the fraction is computed here).
• VerifyProgress carries a pre-computed overall spanning both passes (via verify_overall_progress) so frontends never need to duplicate that formula.
• Stage and Log are both collapsed into Message(String) since both frontends treat them as human-readable status text.
• Done / Error become Completed / Failed to match conventional naming in UI code.

Variants

Progress

Write progress.

progress is bytes_written / total_bytes clamped to [0.0, 1.0].

Fields

progress: f32

bytes_written: u64

speed_mb_s: f32

VerifyProgress

Verification read-back progress spanning both passes.

overall is in [0.0, 1.0]:

• image pass → [0.0, 0.5]
• device pass → [0.5, 1.0]

Fields

phase: &'static str

overall: f32

bytes_read: u64

total_bytes: u64

speed_mb_s: f32

Message(String)

Human-readable status text (stage label or log line).

Completed

The flash pipeline finished successfully.

Failed(String)

The flash pipeline failed; the string is a human-readable error.

Trait Implementations

impl Clone for FlashUpdate

fn clone(&self) -> FlashUpdate

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FlashUpdate

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<FlashEvent> for FlashUpdate

fn from(event: FlashEvent) -> Self

Convert a raw pipeline FlashEvent into a FlashUpdate.

• Progress raw byte counts → normalised 0.0–1.0 fraction.
• VerifyProgress per-pass fraction → overall 0.0–1.0 via verify_overall_progress.
• Stage display string and Log string → Message.
• Done → Completed, Error → Failed.
