Enum DataDirection 

#[non_exhaustive]
pub enum DataDirection {
    None,
    Read,
    Write,
}

Direction of the data phase that follows a command, if any.

Marked #[non_exhaustive]: bidirectional / control-stream variants may be added before 1.0.

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.

None

No data phase follows this command.

Read

The host reads data from the card after the command response.

Write

The host writes data to the card after the command response.

Implementations

impl DataDirection

pub const fn is_none(self) -> bool

Returns true if this command has no data phase.

Trait Implementations

impl Clone for DataDirection

fn clone(&self) -> DataDirection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataDirection

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

Formats the value using the given formatter.

impl PartialEq for DataDirection

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