Function renameZ [src]
Prototype
pub fn renameZ(old_path: [*:0]const u8, new_path: [*:0]const u8) RenameError!void Parameters
old_path: [*:0]const u8new_path: [*:0]const u8 Possible Errors
In WASI, this error may occur when the file descriptor does not hold the required rights to rename a resource by path relative to it.
On Windows, this error may be returned instead of PathAlreadyExists when renaming a directory over an existing directory.
On Windows, antivirus software is enabled by default. It can be disabled, but Windows Update sometimes ignores the user's preference and re-enables it. When enabled, antivirus software on Windows intercepts file system operations and makes them significantly slower in addition to possibly failing with this error code.
WASI-only; file paths must be valid UTF-8.
Windows-only; file paths provided by the user must be valid WTF-8. https://simonsapin.github.io/wtf-8/
On Windows, \\server or \\server\share was not found.
The Operating System returned an undocumented error code.
This error is in theory not possible, but it would be better to handle this error than to invoke undefined behavior.
When this error code is observed, it usually means the Zig Standard Library needs a small patch to add the error code to the error set for the respective function.
