Struct BlobId

pub struct BlobId(Id);

An Id identifying a “blob”

Tuple Fields

0: Id

Methods from Deref<Target = Id>

pub fn is_null(&self) -> bool

Checks if the Id is zero

Examples

use rustic_core::Id;

let id = Id::from_hex("0000000000000000000000000000000000000000000000000000000000000000").unwrap();

assert!(id.is_null());

pub fn blob_matches_reader(&self, length: usize, r: &mut impl Read) -> bool

Checks if this Id matches the content of a reader

Arguments

• length - The length of the blob
• r - The reader to check

Returns

true if the SHA256 matches, false otherwise

pub fn as_u32(&self) -> u32

returns the first 4 bytes as u32 (interpreted as little endian)

Converts to this type from the input type.

impl From<BlobId> for TreeId

fn from(id: BlobId) -> Self

Converts to this type from the input type.

impl From<DataId> for BlobId

fn from(id: DataId) -> Self

Converts to this type from the input type.

type Err = <Id as FromStr>::Err

The associated error which can be returned from parsing.

fn from_str(src: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for BlobId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for BlobId

fn cmp(&self, other: &BlobId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.
