Struct Config

pub struct Config { /* private fields */ }

Line configuration objects.

The line-config object contains the configuration for lines that can be used in two cases:

• when making a line request
• when reconfiguring a set of already requested lines.

A new line-config object is empty. Using it in a request will lead to an error. In order for a line-config to become useful, it needs to be assigned at least one offset-to-settings mapping by calling ::gpiod_line_config_add_line_settings.

When calling ::gpiod_chip_request_lines, the library will request all offsets that were assigned settings in the order that they were assigned.

Implementations

impl Config

pub fn new() -> Result<Self>

Create a new line config object.

pub fn reset(&mut self)

Resets the entire configuration stored in the object. This is useful if the user wants to reuse the object without reallocating it.

pub fn add_line_settings( &mut self, offsets: &[Offset], settings: Settings, ) -> Result<&mut Self>

Add line settings for a set of offsets.

pub fn set_output_values(&mut self, values: &[Value]) -> Result<&mut Self>

Set output values for a number of lines.

pub fn line_settings(&self) -> Result<SettingsMap>

Get a mapping of offsets to line settings stored by this object.

Trait Implementations

impl Debug for Config

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

Formats the value using the given formatter.

impl Drop for Config

fn drop(&mut self)

Free the line config object and release all associated resources.

impl PartialEq for Config

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