Enum async_std_gpiod::Bias

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

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

Disabled bias (default)

PullUp

Pull line up

PullDown

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,

Feeds a slice of this type into the given Hasher.

impl PartialEq<Bias> 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.
