OpenOptions

rama::utils::fs

Struct OpenOptions

pub struct OpenOptions { /* private fields */ }

Available on crate feature std only.

Expand description

Options to open a file with async path-traversal protection.

Mirrors the access-mode setters of [tokio::fs::OpenOptions] (read/write/append/truncate/create/create_new) and adds jail to confine every opened path to a trusted root directory.

Implementations§

impl OpenOptions

pub fn new() -> OpenOptions

Available on crate features grpc and http only.

Create a new set of options with every flag disabled, matching [tokio::fs::OpenOptions::new]. Enable at least one access mode (e.g. read) before calling open.

pub fn read(&mut self, read: bool) -> &mut OpenOptions

Available on crate features grpc and http only.

Set the option for read access.

pub fn write(&mut self, write: bool) -> &mut OpenOptions

Available on crate features grpc and http only.

Set the option for write access.

pub fn append(&mut self, append: bool) -> &mut OpenOptions

Available on crate features grpc and http only.

Set the option for append mode.

pub fn truncate(&mut self, truncate: bool) -> &mut OpenOptions

Available on crate features grpc and http only.

Set the option for truncating a previous file.

pub fn create(&mut self, create: bool) -> &mut OpenOptions

Available on crate features grpc and http only.

Set the option to create a new file, or open it if it already exists.

pub fn create_new(&mut self, create_new: bool) -> &mut OpenOptions

Available on crate features grpc and http only.

Set the option to create a new file, failing if it already exists.

pub fn jail(&mut self, root: impl Into<PathBuf>) -> &mut OpenOptions

Available on crate features grpc and http only.

Confine every opened path to within root.

The path passed to open is then interpreted as relative to root; absolute paths are rejected, and the resolved path must remain within root or the open fails with UnsafePathError::EscapesRoot. root must exist when opening.

pub fn symlinks(&mut self, policy: SymlinkPolicy) -> &mut OpenOptions

Available on crate features grpc and http only.

Set how symbolic links are treated within the jail root.

Defaults to SymlinkPolicy::RestrictToRoot. Has no effect unless a jail root is configured.

pub fn created_file_permissions( &mut self, permissions: CreatedFilePermissions, ) -> &mut OpenOptions

Available on crate features grpc and http only.

Set permissions used when this open operation creates a new file.

pub async fn open(&self, path: impl AsRef<Path>) -> Result<File, Error>

Available on crate features grpc and http only.

Open the file at path with the configured options, after validating it against path-traversal attacks.
