Struct PrefetchFromObjectStoreRequest

pub struct PrefetchFromObjectStoreRequest {
    pub url: String,
    pub store_options: HashMap<String, String>,
    pub location: String,
    pub range_start: Option<u64>,
    pub range_end: Option<u64>,
}

Fields

url: String

Url of the object store. eg. s3://bucket

store_options: HashMap<String, String>

Config options for the object store For S3, this might include “access_key_id”, “secret_access_key”, etc.

location: String

Location of the file within the object store. eg. path/to/file.parquet

range_start: Option<u64>

The start byte offset of the range to prefetch (inclusive) If not specified, prefetch from the beginning of the file

range_end: Option<u64>

The end byte offset of the range to prefetch (exclusive) If not specified, prefetch until the end of the file

Implementations

impl PrefetchFromObjectStoreRequest

pub fn range_start(&self) -> u64

fn default() -> Self

Returns the “default value” for a type.

impl Message for PrefetchFromObjectStoreRequest

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

impl PartialEq for PrefetchFromObjectStoreRequest

fn eq(&self, other: &PrefetchFromObjectStoreRequest) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
