Struct Handle 

pub struct Handle(/* private fields */);

Available on crate feature ustr_handles only.

A node handle string backed by an interned Ustr.

This provides O(1) equality checks and zero-cost conversion to C strings.

Implementations

impl Handle

pub fn new(s: &str) -> Self

Create a new handle from a string slice.

pub fn as_str(&self) -> &str

Get the handle as a string slice.

pub fn as_char_ptr(&self) -> *const c_char

Get the handle as a C string pointer.

The returned pointer is valid for the lifetime of the Ustr cache (effectively ’static for interned strings).

Trait Implementations

impl Clone for Handle

fn clone(&self) -> Handle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Handle

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

Formats the value using the given formatter.

impl From<&str> for Handle

fn from(s: &str) -> Self

Converts to this type from the input type.

impl Hash for Handle

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Handle

fn eq(&self, other: &Handle) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
