Struct HookSet 

pub struct HookSet { /* private fields */ }

An ordered list of hooks to attach to an agent.

Hooks at the same HookPoint fire in registration order.

Implementations

impl HookSet

pub const fn new() -> Self

Create an empty hook set.

pub fn push(&mut self, entry: HookEntry) -> Result<(), Error>

Register a hook.

If a hook with the same name AND hook point already exists, it is replaced and a warning is logged.

Errors

Returns Err if the entry fails validation (empty name or callback_id).

pub fn at_point(&self, point: HookPoint) -> impl Iterator<Item = &HookEntry>

Iterate over hooks at a specific point, in registration order.

pub fn iter(&self) -> impl Iterator<Item = &HookEntry>

Iterate over all hooks.

pub const fn len(&self) -> usize

Number of registered hooks.

pub const fn is_empty(&self) -> bool

Whether the set is empty.

Trait Implementations

impl Clone for HookSet

fn clone(&self) -> HookSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HookSet

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

Formats the value using the given formatter.

impl Default for HookSet

fn default() -> HookSet

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for HookSet

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&HookSet> for Vec<HookEntry>

fn from(set: &HookSet) -> Self

Converts to this type from the input type.

impl From<HookSet> for Vec<HookEntry>

fn from(set: HookSet) -> Self

impl<const N: usize> From<[HookEntry; N]> for HookSet

fn from(entries: [HookEntry; N]) -> Self

Converts to this type from the input type.

impl FromIterator<HookEntry> for HookSet

fn from_iter<T: IntoIterator<Item = HookEntry>>(iter: T) -> Self

Creates a value from an iterator.

impl IntoIterator for HookSet

type Item = HookEntry

The type of the elements being iterated over.

type IntoIter = IntoIter<<HookSet as IntoIterator>::Item>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl Serialize for HookSet

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
