Borrowed(&'a [Nlattr<T, Vec<u8>>])

Vector reference

Methods

impl<'a, T> AttrHandle<'a, T> where
    T: NlAttrType, 

pub fn new(vec: Vec<Nlattr<T, Vec<u8>>>) -> Self

Create new AttrHandle

pub fn new_borrowed(vec: &'a [Nlattr<T, Vec<u8>>]) -> Self

Create new borrowed AttrHandle

pub fn get_slice(&self) -> &[Nlattr<T, Vec<u8>>]

Get the underlying Vec as a reference

pub fn get_vec_mut(&mut self) -> Option<&mut Vec<Nlattr<T, Vec<u8>>>>

Get the underlying Vec as a mutable reference or return None

pub fn size(&self) -> usize

Get size of buffer required to hold attributes

pub fn iter(&self) -> Iter<Nlattr<T, Vec<u8>>>

If attributes are parsed, pass back iterator over attributes

pub fn get_nested_attributes<S>(
    &mut self,
    subattr: T
) -> Result<AttrHandle<S>, NlError> where
    S: NlAttrType, 

Get the payload of an attribute as a handle for parsing nested attributes

pub fn get_attribute<'b>(&'b self, t: T) -> Option<&'b Nlattr<T, Vec<u8>>>

Get nested attributes from a parsed handle

pub fn get_attribute_mut<'b>(
    &'b mut self,
    t: T
) -> Option<&'b mut Nlattr<T, Vec<u8>>>

Mutably get nested attributes from a parsed handle

pub fn get_attr_payload_as<R>(&self, attr: T) -> Result<R, DeError> where
    R: Nl, 

Parse binary payload as a type that implements Nl using deserialize with an option size hint
