Description: API documentation for the Rust `PermissionsExt` trait in crate `std`.
Keywords: rust, rustlang, rust-lang, PermissionsExt

# 1.1.0[−][src]Trait std::os::unix::fs::PermissionsExt

    pub trait PermissionsExt {
        fn mode(&self) -> u32;
        fn set_mode(&mut self, mode: u32);
        fn from_mode(mode: u32) -> Self;
    }

This is supported on Unix only.

Unix-specific extensions to `fs::Permissions`.

## Required methods

### `fn mode(&self) -> u32`

This is supported on Unix only.

Returns the underlying raw `st_mode` bits that contain the standard Unix permissions for this file.

# Examples

    use std::fs::File;
    use std::os::unix::fs::PermissionsExt;

    fn main() -> std::io::Result<()> {
        let f = File::create("foo.txt")?;
        let metadata = f.metadata()?;
        let permissions = metadata.permissions();

        println!("permissions: {}", permissions.mode());
        Ok(()) }Run

### `fn set_mode(&mut self, mode: u32)`

This is supported on Unix only.

Sets the underlying raw bits for this set of permissions.

# Examples

    use std::fs::File;
    use std::os::unix::fs::PermissionsExt;

    fn main() -> std::io::Result<()> {
        let f = File::create("foo.txt")?;
        let metadata = f.metadata()?;
        let mut permissions = metadata.permissions();

        permissions.set_mode(0o644); // Read/write for owner and read for others.
        assert_eq!(permissions.mode(), 0o644);
        Ok(()) }Run

### `fn from_mode(mode: u32) -> Self`

This is supported on Unix only.

Creates a new instance of `Permissions` from the given set of Unix permission bits.

# Examples

    use std::fs::Permissions;
    use std::os::unix::fs::PermissionsExt;

    // Read/write for owner and read for others.
    let permissions = Permissions::from_mode(0o644);
    assert_eq!(permissions.mode(), 0o644);Run

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
