Trait AtomicWriteExt 

pub trait AtomicWriteExt {
    // Required method
    fn atomic_write<F>(&self, write_fn: F) -> WallSwitchResult<()>
       where F: FnOnce(&Path) -> WallSwitchResult<()>;
}

An extension trait to perform filesystem-safe, atomic file writes.

Required Methods

fn atomic_write<F>(&self, write_fn: F) -> WallSwitchResult<()>

where F: FnOnce(&Path) -> WallSwitchResult<()>,

Writes content to a temporary file via a closure, then atomically renames it to the destination path.

The temporary file is guaranteed to be created in the same directory as the target path, satisfying POSIX requirements for atomic renames.

Errors

Returns a WallSwitchError::IOError if directory creation, the write closure, or the final rename swap fails.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
