# Function tokio::fs::create_dir_all [−] [src]

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

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

This is an async version of `std::fs::create_dir_all`

# 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 tokio::fs;

    #[tokio::main]
    async fn main() -> std::io::Result<()> {
        fs::create_dir_all("/some/dir").await?;
        Ok(())
    }
