Struct tvix_eval::StdIO

pub struct StdIO;

Implementation of EvalIO that simply uses the equivalent standard library functions, i.e. does local file-IO.

Trait Implementations

impl EvalIO for StdIO

fn path_exists(&self, path: &Path) -> Result<bool, Error>

Verify whether the file at the specified path exists.

fn read_to_string(&self, path: &Path) -> Result<String, Error>

Read the file at the specified path to a string.

fn read_dir(&self, path: &Path) -> Result<Vec<(Bytes, FileType)>, Error>

Read the directory at the specified path and return the names of its entries associated with their FileType.

fn import_path(&self, path: &Path) -> Result<PathBuf, Error>

Import the given path. What this means depends on the implementation, for example for a std::io-based implementation this might be a no-op, while for a Tvix store this might be a copy of the given files to the store.

fn store_dir(&self) -> Option<String>

Returns the root of the store directory, if such a thing exists in the evaluation context.
