Struct HookSlot

Source

pub struct HookSlot {
    pub programs: Vec<LoadedProgram>,
    pub runner: HookFn,
}

Expand description

A slot for a single hook point, holding its attached programs and runner.

Fields§

§programs: Vec<LoadedProgram>§runner: HookFn

Function pointer — points to hook_noop when empty, [hook_has_programs] when programs are attached.

Implementations§

Source §

impl HookSlot

Source

pub fn update_runner(&mut self)

Update the runner pointer based on whether programs are present.

Source

pub fn attach(&mut self, program: LoadedProgram)

Attach a program to this slot. Maintains descending priority order.

Source

pub fn detach(&mut self, name: &str) -> Option<LoadedProgram>

Detach a program by name. Returns the removed program, if found.

Source

pub fn has_programs(&self) -> bool

Returns true if this slot has programs attached (fast check).
