Struct Checksum 

pub struct Checksum {
    pub crc32: Option<String>,
    pub crc32c: Option<String>,
    pub crc64_nvme: Option<String>,
    pub sha1: Option<String>,
    pub sha256: Option<String>,
}

Base64-encoded checksums returned by S3.

Fields

crc32: Option<String>

Base64-encoded CRC-32 value.

crc32c: Option<String>

Base64-encoded CRC-32C value.

crc64_nvme: Option<String>

Base64-encoded CRC-64/NVME value.

sha1: Option<String>

Base64-encoded SHA-1 value.

sha256: Option<String>

Base64-encoded SHA-256 value.

Implementations

impl Checksum

pub fn calculate( algorithm: ChecksumAlgorithm, bytes: &[u8], ) -> Result<Self, ChecksumCalculationError>

Calculates one checksum over bytes using standard S3 wire encoding.

CRC32, CRC32C, CRC64NVME, and SHA-256 are supported. SHA-1 remains an accepted wire value but is not calculated locally.

Errors

Returns an error when local calculation is unavailable for algorithm.

Trait Implementations

impl Clone for Checksum

fn clone(&self) -> Checksum

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Checksum

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Checksum

fn default() -> Checksum

Returns the “default value” for a type.

impl Eq for Checksum

impl PartialEq for Checksum

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

Equality operator ==.

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

Inequality operator !=.
