Struct Request

pub struct Request { /* private fields */ }

Line request operations

Allows interaction with a set of requested lines.

Implementations

impl Request

pub fn num_lines(&self) -> usize

Get the number of lines in the request.

pub fn offsets(&self) -> Vec<Offset>

Get the offsets of lines in the request.

pub fn value(&self, offset: Offset) -> Result<Value>

Get the value (0 or 1) of a single line associated with the request.

pub fn values_subset(&self, offsets: &[Offset]) -> Result<ValueMap>

Get values of a subset of lines associated with the request.

pub fn values(&self) -> Result<ValueMap>

Get values of all lines associated with the request.

pub fn set_value(&mut self, offset: Offset, value: Value) -> Result<&mut Self>

Set the value of a single line associated with the request.

pub fn set_values_subset(&mut self, map: ValueMap) -> Result<&mut Self>

Set values of a subset of lines associated with the request.

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

Set values of all lines associated with the request.

pub fn reconfigure_lines(&mut self, lconfig: &Config) -> Result<&mut Self>

Update the configuration of lines associated with the line request.

pub fn wait_edge_events(&self, timeout: Option<Duration>) -> Result<bool>

Wait for edge events on any of the lines associated with the request.

pub fn read_edge_events<'a>(&self, buffer: &'a mut Buffer) -> Result<Events<'a>>

Get a number of edge events from a line request.

This function will block if no event was queued for the line.

Trait Implementations

impl AsRawFd for Request

fn as_raw_fd(&self) -> i32

Get the file descriptor associated with the line request.

impl Debug for Request

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

Formats the value using the given formatter.

impl Drop for Request

fn drop(&mut self)

Release the requested lines and free all associated resources.

impl PartialEq for Request

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