Struct tvix_eval::StdIO

source ·
pub struct StdIO;
Expand description

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

Trait Implementations§

source§

impl EvalIO for StdIO

source§

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

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

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

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

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

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

fn read_dir(&self, path: &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: &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
