ModuleParamAccess

kernel::module_param

Struct ModuleParamAccess 

Source 
pub struct ModuleParamAccess<T> { /* private fields */ }
Expand description

A wrapper for kernel parameters.

This type is instantiated by the module! macro when module parameters are defined. You should never need to instantiate this type directly.

Note: This type is pub because it is used by module crates to access parameter values.

Implementations§

Source§

impl<T> ModuleParamAccess<T>

Source

pub fn value(&self) -> &T

Get a shared reference to the parameter value.

Source

pub const fn as_void_ptr(&self) -> *mut c_void

Get a mutable pointer to self.

NOTE: In most cases it is not safe deref the returned pointer.
