Struct ObjectChecksums

#[non_exhaustive]
pub struct ObjectChecksums {
    pub crc32c: Option<u32>,
    pub md5_hash: Bytes,
    /* private fields */
}

Message used for storing full (not subrange) object checksums.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

crc32c: Option<u32>

CRC32C digest of the object data. Computed by the Cloud Storage service for all written objects. If set in a WriteObjectRequest, service will validate that the stored object matches this checksum.

md5_hash: Bytes

Optional. 128 bit MD5 hash of the object data. For more information about using the MD5 hash, see [https://cloud.google.com/storage/docs/hashes-etags#json-api][Hashes and ETags: Best Practices]. Not all objects will provide an MD5 hash. For example, composite objects provide only crc32c hashes. This value is equivalent to running cat object.txt | openssl md5 -binary

Implementations

impl ObjectChecksums

pub fn new() -> Self

pub fn set_crc32c<T>(self, v: T) -> Self

where T: Into<u32>,

Sets the value of crc32c.

pub fn set_or_clear_crc32c<T>(self, v: Option<T>) -> Self

where T: Into<u32>,

Sets or clears the value of crc32c.

pub fn set_md5_hash<T: Into<Bytes>>(self, v: T) -> Self

Sets the value of md5_hash.

Trait Implementations

impl Clone for ObjectChecksums

fn clone(&self) -> ObjectChecksums

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ObjectChecksums

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

Formats the value using the given formatter.

impl Default for ObjectChecksums

fn default() -> ObjectChecksums

Returns the “default value” for a type.

impl Message for ObjectChecksums

fn typename() -> &'static str

The typename of this message.

impl PartialEq for ObjectChecksums

fn eq(&self, other: &ObjectChecksums) -> 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.
