Struct cap_std::fs::Metadata

source · [−]

pub struct Metadata { /* private fields */ }

Expand description

Metadata information about a file.

This corresponds to std::fs::Metadata.

We need to define our own version because the libstd `Metadata` doesn't have a public constructor that we can use.

Implementations

source

impl Metadata

source

pub fn from_file(file: &File) -> Result<Metadata, Error>

Constructs a new instance of Self from the given std::fs::File.

source

pub fn from_just_metadata(std: Metadata) -> Metadata

Constructs a new instance of Self from the given std::fs::Metadata.

As with the comments in std::fs::Metadata::volume_serial_number and nearby functions, some fields of the resulting metadata will be None.

source

pub const fn file_type(&self) -> FileType

Returns the file type for this metadata.

This corresponds to std::fs::Metadata::file_type.

source

pub fn is_dir(&self) -> bool

Returns true if this metadata is for a directory.

This corresponds to std::fs::Metadata::is_dir.

source

pub fn is_file(&self) -> bool

Returns true if this metadata is for a regular file.

This corresponds to std::fs::Metadata::is_file.

source

pub fn is_symlink(&self) -> bool

Returns true if this metadata is for a symbolic link.

This corresponds to std::fs::Metadata::is_symlink.

source

pub const fn len(&self) -> u64

Returns the size of the file, in bytes, this metadata is for.

This corresponds to std::fs::Metadata::len.

source

pub fn permissions(&self) -> Permissions

Returns the permissions of the file this metadata is for.

This corresponds to std::fs::Metadata::permissions.

source

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

Returns the last modification time listed in this metadata.

This corresponds to std::fs::Metadata::modified.

source

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

Returns the last access time of this metadata.

This corresponds to std::fs::Metadata::accessed.

source

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

Returns the creation time listed in this metadata.

This corresponds to std::fs::Metadata::created.
