# Function std::fs::create_dir_all

1.0.0 · source ·

    pub fn create_dir_all<P: AsRef<Path>>(path: P) -> Result<()>

Expand description

Recursively create a directory and all of its parent components if they are missing.

## Platform-specific behavior

This function currently corresponds to the `mkdir` function on Unix and the `CreateDirectory` function on Windows. Note that, this may change in the future.

## Errors

This function will return an error in the following situations, but is not limited to just these cases:

- If any directory in the path specified by `path` does not already exist and it could not be created otherwise. The specific error conditions for when a directory is being created (after it is determined to not exist) are outlined by `fs::create_dir`.

Notable exception is made for situations where any of the directories specified in the `path` could not be created as it was being created concurrently. Such cases are considered to be successful. That is, calling `create_dir_all` concurrently from multiple threads or processes is guaranteed not to fail due to a race condition with itself.

## Examples

    use std::fs;

    fn main() -> std::io::Result<()> {
        fs::create_dir_all("/some/dir")?;
        Ok(())
    }
