Struct flatdata::Handle

pub struct Handle<'a, T: 'a> { /* fields omitted */ }

Handle to a flatdata struct for read-only fields access.

Wraps a flatdata struct and provides a read-only access to its data. A handle automatically deref's to a reference of the underlying struct. It is used to track the lifetime of the wrapped object, since a generated flatdata struct does not tracks the lifetime of the underlying data itself. A handle is similar to const references, it is possible to have several of them in scope, but not a const and mutable handle at the same time, cf. HandleMut.

Methods

impl<'a, T: 'a> Handle<'a, T>

pub fn new(t: T) -> Self

Trait Implementations

impl<'a, T: Clone + 'a> Clone for Handle<'a, T>

fn clone(&self) -> Handle<'a, T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a, T: PartialEq + 'a> PartialEq for Handle<'a, T>

fn eq(&self, other: &Handle<'a, T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Handle<'a, T>) -> bool

This method tests for !=.

impl<'a, T> Deref for Handle<'a, T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<'a, T: Debug> Debug for Handle<'a, T>

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
