Struct gpiod_core::Internal

pub struct Internal<T>(/* private fields */);

Wrapper to hide internals

Implementations

impl Internal<ValuesInfo>

pub fn get_values<T: AsValuesMut>( &self, fd: RawFd, values: &mut T ) -> Result<()>

pub fn set_values<T: AsValues>(&self, fd: RawFd, values: T) -> Result<()>

impl Internal<ChipInfo>

pub fn from_fd(fd: RawFd) -> Result<Self>

pub fn line_info(&self, fd: RawFd, line: LineId) -> Result<LineInfo>

Request the info of a specific GPIO line.

pub fn request_lines<Direction: DirectionType>( &self, fd: RawFd, options: Options<Direction, impl AsRef<[LineId]>, impl AsRef<str>> ) -> Result<(Internal<ValuesInfo>, RawFd)>

Request the GPIO chip to configure the lines passed as argument as outputs

Calling this operation is a precondition to being able to set the state of the GPIO lines. All the lines passed in one request must share the output mode and the active state.

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T> DerefMut for Internal<T>
