Struct async_std::fs::Metadata

pub struct Metadata { /* fields omitted */ }

Metadata for a file or directory.

Metadata is returned by metadata and symlink_metadata.

This type is a re-export of std::fs::Metadata.

Methods

impl Metadata

pub fn file_type(&self) -> FileType

Returns the file type from this metadata.

Examples

use async_std::fs;

let metadata = fs::metadata("a.txt").await?;
println!("{:?}", metadata.file_type());

pub fn is_dir(&self) -> bool

Returns true if this metadata is for a regular directory.

If this metadata is for a symbolic link, this method returns false.

Examples

use async_std::fs;

let metadata = fs::metadata(".").await?;
println!("{:?}", metadata.is_dir());

pub fn is_file(&self) -> bool

Returns true if this metadata is for a regular file.

If this metadata is for a symbolic link, this method returns false.

Examples

use async_std::fs;

let metadata = fs::metadata("a.txt").await?;
println!("{:?}", metadata.is_file());

pub fn len(&self) -> u64

Returns the file size in bytes.

Examples

use async_std::fs;

let metadata = fs::metadata("a.txt").await?;
println!("{}", metadata.len());

pub fn permissions(&self) -> Permissions

Returns the permissions from this metadata.

Examples

use async_std::fs;

let metadata = fs::metadata("a.txt").await?;
println!("{:?}", metadata.permissions());

pub fn modified(&self) -> Result<SystemTime>

Returns the last modification time.

Errors

This data may not be available on all platforms, in which case an error will be returned.

Examples

use async_std::fs;

let metadata = fs::metadata("a.txt").await?;
println!("{:?}", metadata.modified());

pub fn accessed(&self) -> Result<SystemTime>

Returns the last access time.

Errors

This data may not be available on all platforms, in which case an error will be returned.

Examples

use async_std::fs;

let metadata = fs::metadata("a.txt").await?;
println!("{:?}", metadata.accessed());

pub fn created(&self) -> Result<SystemTime>

Returns the creation time.

Errors

This data may not be available on all platforms, in which case an error will be returned.

Examples

use async_std::fs;

let metadata = fs::metadata("a.txt").await?;
println!("{:?}", metadata.created());
