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 validates 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 Data validation and change detection. Not all objects 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.

Example

let x = ObjectChecksums::new().set_crc32c(42_u32);

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

where T: Into<u32>,

Sets or clears the value of crc32c.

Example

let x = ObjectChecksums::new().set_or_clear_crc32c(Some(42_u32));
let x = ObjectChecksums::new().set_or_clear_crc32c(None::<u32>);

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

Sets the value of md5_hash.

Example

let x = ObjectChecksums::new().set_md5_hash(bytes::Bytes::from_static(b"example"));

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.
