Enum gpiocdev::AbiVersion

pub enum AbiVersion {
    V1,
    V2,
}

The uAPI ABI versions available to interact with the kernel.

Two versions of the Linux GPIO uAPI ABI currently exist, with v1 being released in Linux v4.8 and v2 being released in Linux v5.10. Both versions of the uAPI ABI are supported by gpiocdev, both individually and combined, with the library defaulting to v2.

The v1 uAPI can be selected as a feature for applications where v2 may be unavailable.

• V2 is the current ABI and is used by default.
• V1 is more restrictive than V2, so some information and features are unavailable, but the ABI itself is more widely available.

Trait Implementations

impl Clone for AbiVersion

fn clone(&self) -> AbiVersion

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AbiVersion

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

Formats the value using the given formatter.

impl Default for AbiVersion

fn default() -> Self

Returns the “default value” for a type.

impl Display for AbiVersion

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

Formats the value using the given formatter.

impl PartialEq<AbiVersion> for AbiVersion

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

This method tests for self and other values to be equal, and is used by ==.

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

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