Enum ParquetSourceLocation 

pub enum ParquetSourceLocation {
    LocalPath(PathBuf),
    ObjectStoreUri {
        scheme: String,
        uri: String,
    },
}

Explicit location/read-capability model for native Parquet sources.

Variants

LocalPath(PathBuf)

Local filesystem path readable by cuDF local Parquet readers.

ObjectStoreUri

Object-store URI plus parsed scheme.

Fields

scheme: String

Lowercase object-store scheme such as s3.

uri: String

Original object-store URI.

Implementations

impl ParquetSourceLocation

pub fn local_path(path: impl Into<PathBuf>) -> Self

Build a local filesystem source location.

pub fn object_store_uri(uri: impl Into<String>) -> Result<Self, String>

Build a supported object-store URI location.

Currently only s3://... is accepted. Errors are stable reason strings such as missing_uri_scheme or unsupported_uri_scheme:<scheme>.

pub fn reader_path(&self) -> String

Path or URI string passed to lower-level readers.

pub fn read_capability(&self) -> String

Stable read-capability diagnostic string.

pub fn is_local_path(&self) -> bool

Whether this location is a local filesystem path.

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

Borrow the local path when this location is local.

pub fn diagnostic_location(&self) -> String

Redacted diagnostic location. Local paths are preserved; object-store URIs are represented by scheme plus stable hash only.
