Enum gpiod::Bias

#[repr(u8)]
pub enum Bias {
    Disable = 0,
    PullUp = 1,
    PullDown = 2,
}

Input bias of a GPIO line

Sometimes GPIO lines shall be pulled to up (power rail) or down (ground) through resistor to avoid floating level on it.

Variants

Disable = 0

Disabled bias (default)

PullUp = 1

Pull line up

PullDown = 2

Pull line down

Trait Implementations

impl AsRef<str> for Bias

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Bias

fn clone(&self) -> Bias

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Bias

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

Formats the value using the given formatter.

impl Default for Bias

fn default() -> Bias

Returns the “default value” for a type.

impl Display for Bias

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

Formats the value using the given formatter.

impl FromStr for Bias

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Bias, Error>

Parses a string s to return a value of this type.

impl Hash for Bias

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Bias

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

impl Copy for Bias

impl Eq for Bias

impl StructuralPartialEq for Bias
