RundownGuard

Struct RundownGuard 

Source
pub struct RundownGuard<'r> { /* private fields */ }
Expand description

An RAII implementation of a “scoped lock” pattern, but specialized to the needs of run-down protection. When this structure is dropped (falls out of scope), the rundown protection reference that was previously acquired is released.

This structure is created by the try_acquire method on RundownRef.

This type attempts to follow the RAII guidance here: https://github.com/rust-unofficial/patterns/blob/master/patterns/RAII.md

Implementations§

Source§

impl<'r> RundownGuard<'r>

Source

pub const fn new(owned_run_down_ref: &'r RundownRef) -> RundownGuard<'r>

Creates a new RundownGuard which owns an instance of run-down protection on the RundownRef provided.

§Arguments
  • owned_run_down_ref - The run-down reference to release when the guard goes out of scope.
