sysfs class entity attribute type extension

Provided Methods

fn capable<C: Capabilities<A, Self>>(&self, capabilities: C) -> bool

Returns true if self is capable of the provided capabilities

fn attribute<T: FromStr<Err = E>, E>( &self, attr: A, ) -> Result<T, EitherErr2<Error, E>>

Get an attribute on the entity

fn set<V: ToString>(&self, attr: A, value: V) -> IoResult<()>

Set an attribute on the entity

fn read_value(&self, attr: &A) -> IoResult<Vec<u8>>

Read entity attribute value

fn write_value(&self, attr: &A, value: &[u8]) -> IoResult<()>

Write entity attribute value

fn exists(&self, attr: &A) -> bool

Returns true when the entity has the attribute

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.
