Struct DetachmentBlocker 

Source 
pub struct DetachmentBlocker;
Expand description

Use for accessing the thread local that determines whether or not DOM futures being dropped should try to detach their nodes from the parent. Rust’s drop glue drops struct fields in order of declaration, so as the last field, we put a struct that will unset the thread local when dropped.

Implementations§

Source§

impl DetachmentBlocker

Source

pub fn block_until_drop(&self) -> bool

Block the detachment, returning true iff it was already blocked. If the detachment was not previously blocked, then this instance of DetachmentBlocker will “own” the blocking, and detachment will be unblocked when this instance is dropped.
