pub struct FileIO { /* private fields */ }
Expand description
FileIO implementation, used to manipulate files in underlying storage.
§Note
All path passed to FileIO
must be absolute path starting with scheme string used to construct FileIO
.
For example, if you construct FileIO
with s3a
scheme, then all path passed to FileIO
must start with s3a://
.
Supported storages:
Storage | Feature Flag | Schemes |
---|---|---|
Local file system | storage-fs | file |
Memory | storage-memory | memory |
S3 | storage-s3 | s3 , s3a |
GCS | storage-gcs | gcs |
Implementations§
source§impl FileIO
impl FileIO
sourcepub fn from_path(path: impl AsRef<str>) -> Result<FileIOBuilder>
pub fn from_path(path: impl AsRef<str>) -> Result<FileIOBuilder>
Try to infer file io scheme from path. See FileIO
for supported schemes.
- If it’s a valid url, for example
s3://bucket/a
, url scheme will be used, and the rest of the url will be ignored. - If it’s not a valid url, will try to detect if it’s a file path.
Otherwise will return parsing error.
