// Copyright IBM Corp. 2014, 2026 // SPDX-License-Identifier: BUSL-1.1 //go:build !windows // +build !windows package replacefile import ( "os" ) // AtomicRename renames from the source path to the destination path, // atomically replacing any file that might already exist at the destination. // // Typically this operation can succeed only if the source and destination // are within the same physical filesystem, so this function is best reserved // for cases where the source and destination exist in the same directory and // only the local filename differs between them. // // The Unix implementation of AtomicRename relies on the atomicity of renaming // that is required by the ISO C standard, which in turn assumes that Go's // implementation of rename is calling into a system call that preserves that // guarantee. func AtomicRename(source, destination string) error { // On Unix systems, a rename is sufficiently atomic. return os.Rename(source, destination) }
