Enum libpijul_compat::Hash
[−]
[src]
pub enum Hash { None, Sha512(Sha512), }
The external hash of patches.
Variants
None
None is the hash of the "null patch", which introduced a single root vertex at the beginning of the repository.
Sha512(Sha512)
Patch hashed using the SHA2-512 algorithm.
Methods
impl Hash
[src]
fn from_binary(v: &[u8]) -> Option<Self>
[src]
Get a Hash
from a binary slice. This function does not
compute the digest of anything, it just converts types.
fn from_base58(base58: &str) -> Option<Self>
[src]
Decode a hash from a base58-encoded str
.
fn as_slice(&self) -> &[u8]
[src]
This hash as a slice (nonempty iff SHA512). This method might disappear when new hashes are introduced.
fn as_ref(&self) -> HashRef
[src]
A borrowed version of this Hash
, used for instance to
query the databases.
fn of_slice(buf: &[u8]) -> Hash
[src]
Create a Hash
from the binary slice of the patch contents.
