Struct iceberg::io::FileIO

source ·
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:

StorageFeature FlagSchemes
Local file systemstorage-fsfile
Memorystorage-memorymemory
S3storage-s3s3, s3a
GCSstorage-gcsgcs

Implementations§

source§

impl FileIO

source

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.

source

pub async fn delete(&self, path: impl AsRef<str>) -> Result<()>

Deletes file.

§Arguments
  • path: It should be absolute path starting with scheme string used to construct FileIO.
source

pub async fn remove_all(&self, path: impl AsRef<str>) -> Result<()>

Remove the path and all nested dirs and files recursively.

§Arguments
  • path: It should be absolute path starting with scheme string used to construct FileIO.
source

pub async fn exists(&self, path: impl AsRef<str>) -> Result<bool>

Check file exists.

§Arguments
  • path: It should be absolute path starting with scheme string used to construct FileIO.
source

pub fn new_input(&self, path: impl AsRef<str>) -> Result<InputFile>

§Arguments
  • path: It should be absolute path starting with scheme string used to construct FileIO.
source

pub fn new_output(&self, path: impl AsRef<str>) -> Result<OutputFile>

Creates output file.

§Arguments
  • path: It should be absolute path starting with scheme string used to construct FileIO.
