HookContextCell

Struct HookContextCell 

Source 
pub struct HookContextCell(/* private fields */);
Expand description

A Sync wrapper for single-threaded global HookContextInner access.

SAFETY: This type is only safe to use in single-threaded contexts (e.g., WASM). It implements Sync to allow usage as a static variable, but concurrent access from multiple threads would be undefined behavior.

Implementations§

Source§

impl HookContextCell

Implementation of HookContextCell construction and access.

Source

pub const fn get_inner(&self) -> &'static mut HookContextInner

Returns a mutable reference to the inner HookContextInner.

§Returns
  • &'static mut HookContextInner - A mutable reference to the inner state.
