Enum Phase 

#[non_exhaustive]
pub enum Phase {
    Unspecified,
    Init,
    CommandSend,
    ResponseWait,
    DataWrite,
    DataRead,
    BusyWait,
    Switch,
    Erase,
}

Where in the driver pipeline a fault was observed.

Attached to recoverable Error variants via ErrorContext so callers can distinguish e.g. a CMD0 send timeout from a BusyWait programming timeout without parsing log strings.

Marked #[non_exhaustive]: more phases (e.g. tuning, voltage switch) are expected to land before 1.0, and downstream match sites must keep a _ => ... arm to absorb them without recompiling.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unspecified

Phase was not recorded.

Used as a default placeholder; real driver paths should pick a concrete variant.

Init

Power-up / running CMD0 → ACMD41 / sending CMD2/3/9/7.

CommandSend

Putting the command bytes onto the bus.

ResponseWait

Waiting for the card’s response token / R1–R7 payload.

DataWrite

Streaming a data block to the card (CMD24 / CMD25 etc).

DataRead

Streaming a data block from the card (CMD17 / CMD18 etc).

BusyWait

Polling the card’s busy line / programming status.

Switch

Switching bus speed, width or function (CMD6 / ACMD6).

Erase

Erase sequence (CMD32 / CMD33 / CMD38).

Trait Implementations

impl Clone for Phase

fn clone(&self) -> Phase

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Phase

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

Formats the value using the given formatter.

impl Default for Phase

fn default() -> Phase

Returns the “default value” for a type.

impl Display for Phase

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

Formats the value using the given formatter.

impl PartialEq for Phase

fn eq(&self, other: &Phase) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
