Struct NodeHandle

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

Cheap handle to a registered FlowNode

Implementations

impl NodeHandle

pub fn from_type<N: FlowNodeBase + 'static>() -> NodeHandle

pub fn from_modpath(modpath: &str) -> NodeHandle

pub fn try_from_modpath(modpath: &str) -> Option<NodeHandle>

pub fn new_erased_node(&self) -> Box<dyn FlowNodeBase<Request = Box<[u8]>>>

pub fn modpath(&self) -> &'static str

pub fn try_modpath(&self) -> Option<&'static str>

pub fn dummy() -> NodeHandle

Return a dummy NodeHandle, which will panic if new_erased_node is ever called on it.

Trait Implementations

impl Clone for NodeHandle

fn clone(&self) -> NodeHandle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NodeHandle

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

Formats the value using the given formatter.

impl Hash for NodeHandle

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 Ord for NodeHandle

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for NodeHandle

fn eq(&self, other: &NodeHandle) -> 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.

impl PartialOrd for NodeHandle

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
