Struct ErrorContext 

pub struct ErrorContext {
    pub phase: Phase,
    pub cmd: Option<u8>,
}

Operational context attached to recoverable bus / protocol errors.

Helps callers triage failures: which phase of the SD/MMC pipeline raised the error, and which CMD/ACMD index was being processed at the time, when known.

Fields

phase: Phase

Pipeline phase when the fault was raised.

cmd: Option<u8>

CMD/ACMD index being processed, if applicable.

Implementations

impl ErrorContext

pub const fn new(phase: Phase) -> Self

Build a context with only the phase populated.

pub const fn for_cmd(phase: Phase, cmd: u8) -> Self

Build a context tied to a specific CMD/ACMD index.

Trait Implementations

impl Clone for ErrorContext

fn clone(&self) -> ErrorContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorContext

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

Formats the value using the given formatter.

impl Default for ErrorContext

fn default() -> ErrorContext

Returns the “default value” for a type.

impl PartialEq for ErrorContext

fn eq(&self, other: &ErrorContext) -> 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.
