Struct cap_async_std::fs::File

source · [−]

pub struct File { /* private fields */ }

Expand description

A reference to an open file on a filesystem.

This corresponds to async_std::fs::File.

Note that this File has no open or create methods. To open or create a file, you must first obtain a Dir containing the path, and then call Dir::open or Dir::create.

Implementations

source

impl File

source

pub fn from_std(std: File) -> Self

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

This grants access the resources the async_std::fs::File instance already has access to.

source

pub fn into_std(self) -> File

Consumes self and returns an async_std::fs::File.

source

pub async fn sync_all(&self) -> Result<()>

Attempts to sync all OS-internal metadata to disk.

This corresponds to async_std::fs::File::sync_all.

source

pub async fn sync_data(&self) -> Result<()>

This function is similar to sync_all, except that it may not synchronize file metadata to a filesystem.

This corresponds to async_std::fs::File::sync_data.

source

pub async fn set_len(&self, size: u64) -> Result<()>

Truncates or extends the underlying file, updating the size of this file to become size.

This corresponds to async_std::fs::File::set_len.

source

pub fn metadata(&self) -> Result<Metadata>

Queries metadata about the underlying file.

This corresponds to async_std::fs::File::metadata.

source

pub async fn set_permissions(&self, perm: Permissions) -> Result<()>

Changes the permissions on the underlying file.

This corresponds to async_std::fs::File::set_permissions.

source

pub async fn open_ambient<P: AsRef<Path>>(
path: P,
ambient_authority: AmbientAuthority
) -> Result<Self>

Constructs a new instance of Self in read-only mode by opening the given path as a file using the host process’ ambient authority.

Ambient Authority

This function is not sandboxed and may access any path that the host process has access to.

source

pub async fn open_ambient_with<P: AsRef<Path>>(
 path: P,
 options: &OpenOptions,
 ambient_authority: AmbientAuthority
) -> Result<Self>

Constructs a new instance of Self with the options specified by options by opening the given path as a file using the host process’ ambient authority.

Ambient Authority

This function is not sandboxed and may access any path that the host process has access to.

source

pub fn options() -> OpenOptions

Returns a new OpenOptions object.

This corresponds to [async_std::fs::File::options].
