Struct StorageRoots 

Source 
pub struct StorageRoots { /* private fields */ }
Expand description

Optional roots used to resolve logical input and output paths.

Relative paths are joined to their corresponding root. Absolute paths are always treated as explicit locations and bypass the roots. Relative paths containing .. are rejected so a logical dataset path cannot escape its configured root.

Implementations§

Source§

impl StorageRoots

Source

pub const fn new( input_root: Option<PathBuf>, output_root: Option<PathBuf>, ) -> StorageRoots

Creates a root mapping. Either root may be omitted.

Source

pub fn input_root(&self) -> Option<&Path>

Returns the configured input root, if any.

Source

pub fn output_root(&self) -> Option<&Path>

Returns the configured output root, if any.

Source

pub fn resolve_input(&self, path: impl AsRef<Path>) -> Result<PathBuf, IoError>

Resolves a logical input path against the configured input root.

Source

pub fn resolve_output(&self, path: impl AsRef<Path>) -> Result<PathBuf, IoError>

Resolves a logical output path against the configured output root.

Source

pub fn ensure_output_parent( &self, path: impl AsRef<Path>, ) -> Result<(), IoError>

Creates the parent directory for an explicit output path when needed.

Source

pub fn preflight_output( &self, required_free_bytes: u64, ) -> Result<StoragePreflight, IoError>

Checks the configured output root before opening an external data source.
