Struct async_std::fs::DirBuilder

source ·
pub struct DirBuilder { /* private fields */ }
Expand description

A builder for creating directories with configurable options.

For Unix-specific options, import the os::unix::fs::DirBuilderExt trait.

This type is an async version of std::fs::DirBuilder.

Implementations§

source§

impl DirBuilder

source

pub fn new() -> DirBuilder

Creates a blank set of options.

The recursive option is initially set to false.

Examples
use async_std::fs::DirBuilder;

let builder = DirBuilder::new();
source

pub fn recursive(&mut self, recursive: bool) -> &mut Self

Sets the option for recursive mode.

When set to true, this option means all parent directories should be created recursively if they don’t exist. Parents are created with the same permissions as the final directory.

This option is initially set to false.

Examples
use async_std::fs::DirBuilder;

let mut builder = DirBuilder::new();
builder.recursive(true);
source

pub fn create<P: AsRef<Path>>( &self, path: P ) -> impl Future<Output = Result<()>>

Creates a directory with the configured options.

It is considered an error if the directory already exists unless recursive mode is enabled.

Errors

An error will be returned in the following situations:

  • path already points to an existing file or directory.
  • The current process lacks permissions to create the directory or its missing parents.
  • Some other I/O error occurred.
Examples
use async_std::fs::DirBuilder;

DirBuilder::new()
    .recursive(true)
    .create("./some/directory")
    .await?;
