Implementations

impl MultipartConfig

const DEFAULT_MULTIPART_THRESHOLD: usize = 8_388_608usize

The minimum object size for which we start using multipart upload.

From the official aws cli tool implementation:

https://github.com/aws/aws-cli/blob/2.4.14/awscli/customizations/s3/transferconfig.py#L18-L29

const DEFAULT_MULTIPART_CHUNK_SIZE: usize = 8_388_608usize

The size of each part (except the last) in a multipart upload.

From the official aws cli tool implementation:

https://github.com/aws/aws-cli/blob/2.4.14/awscli/customizations/s3/transferconfig.py#L18-L29

const MAX_SINGLE_UPLOAD_SIZE: usize = 5_497_558_138_880usize

The largest size object creatable in S3.

From https://docs.aws.amazon.com/AmazonS3/latest/userguide/qfacts.html

const MIN_UPLOAD_CHUNK_SIZE: usize = 5_242_880usize

The minimum size of a part in a multipart upload.

This minimum doesn’t apply to the last chunk, which can be any size.

From https://docs.aws.amazon.com/AmazonS3/latest/userguide/qfacts.html

const MIN_PART_NUM: u32 = 1u32

The smallest allowable part number (inclusive).

From https://docs.aws.amazon.com/AmazonS3/latest/userguide/qfacts.html

const MAX_PART_NUM: u32 = 10_000u32

The largest allowable part number (inclusive).
