Struct ModuleCursor

pub struct ModuleCursor<'a> { /* private fields */ }

Implementations

impl<'a> ModuleCursor<'a>

pub fn is_null(&self) -> bool

Returns true if this cursor is pointing to the null object

pub fn get(&self) -> Option<&Function>

Return a reference to the function pointed to by this cursor

If the cursor is pointing to the null object, None is returned

pub fn insert_after(&mut self, function: Box<Function>)

Insert a new function into the module after the cursor.

If the cursor is pointing to the null object, the insert happens at the front of the list.

NOTE: This function will panic if the function violates the validation rules for the module, i.e. must not be attached, follows kernel module rules when applicable.

pub fn insert_before(&mut self, function: Box<Function>)

Insert a new function into the module before the cursor.

If the cursor is pointing to the null object, the insert happens at the end of the list.

NOTE: This function will panic if the function violates the validation rules for the module, i.e. must not be attached, follows kernel module rules when applicable.

pub fn move_next(&mut self)

Moves this cursor to the next function in the module.

If the cursor is pointing to the null object, then this moves the cursor to the front of the list. If at the end of the list, it moves to the null object.

pub fn move_prev(&mut self)

Moves this cursor to the previous function in the module.

If the cursor is pointing to the null object, then this moves the cursor to the end of the list. If at the front of the list, it moves to the null object.

pub fn peek_next(&self) -> Cursor<'_, FunctionListAdapter>

Return a cursor pointing to the next function in the module.

If this cursor is on the null object, then the returned cursor will be on the front of the list. If at the last element, then the returned cursor will on the null object.

pub fn peek_prev(&self) -> Cursor<'_, FunctionListAdapter>

Return a cursor pointing to the previous function in the module.

If this cursor is on the null object, then the returned cursor will be on the end of the list. If at the first element, then the returned cursor will on the null object.

pub fn remove(&mut self) -> Option<Box<Function>>

Removes the current function from the module.

The cursor will be moved to the next function in the module, or the null object if we’re at the end of the module.
