Struct tvix_eval::io::DummyIO

source ·
pub struct DummyIO;
Expand description

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

Trait Implementations§

source§

impl EvalIO for DummyIO

source§

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

Verify whether the file at the specified path exists. Read more
source§

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

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

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. Read more
source§

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. Read more
source§

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

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