Struct DummyIO

pub struct DummyIO;

Dummy implementation of EvalIO, can be used in contexts where IO is not available but code should “pretend” that it is.

Trait Implementations

impl EvalIO for DummyIO

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

Verify whether the file at the specified path exists.

fn open(&self, _: &Path) -> Result<Box<dyn Read>>

Open the file at the specified path to a io::Read.

fn file_type(&self, _: &Path) -> Result<FileType>

Return the FileType of the given path, or an error if it doesn’t exist.

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

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

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

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.
