sysfs entity attribute functionality extension

Provided Methods

fn read_str<E: SysEntity + ?Sized>(&self, entity: &E) -> IoResult<String>

read attribute as string

fn write_str<E: SysEntity + ?Sized>(&self, entity: &E, s: &str) -> IoResult<()>

write attribute string value to sysfsfilter_map

fn parse<T: FromStr<Err = E>, E, ENT: SysEntity + ?Sized>( &self, entity: &ENT, ) -> Result<T, EitherErr2<Error, E>>

read and parse the attribute value

fn path<E: SysEntity + ?Sized>(&self, entity: &E) -> PathBuf

full path to attribute file

fn exists<E: SysEntity + ?Sized>(&self, entity: &E) -> bool

returns true if the path to the attribute file exists

fn read_value<E: SysEntity + ?Sized>(&self, entity: &E) -> IoResult<Vec<u8>>

read attribute value from sysfs

fn write_value<E: SysEntity + ?Sized>( &self, entity: &E, value: &[u8], ) -> IoResult<()>

write attribute value to sysfs

fn readonly<E: SysEntity + ?Sized>(&self, entity: &E) -> bool

Returns true if the attribute is readonly

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
