[−][src]Struct git_hash::owned::Digest
An owned hash identifying objects, most commonly Sha1
Implementations
impl Digest
[src]
Access and conversion
pub fn kind(&self) -> Kind
[src]
Returns the kind of hash used in this Digest
pub fn to_borrowed(&self) -> Digest<'_>
[src]
Return a borrowed version of this instance
pub fn as_slice(&self) -> &[u8]
[src]
Return the raw byte slice representing this hash
pub fn as_mut_slice(&mut self) -> &mut [u8]
[src]
Return the raw mutable byte slice representing this hash
pub fn write_hex_to(&self, mut out: impl Write) -> Result<()>
[src]
Write ourselves to out
in hexadecimal notation
impl Digest
[src]
Sha1 hash specific methods
pub fn from_40_bytes_in_hex(buffer: &[u8]) -> Result<Digest, Error>
[src]
Create an instance from a buffer
of 40 bytes encoded with hexadecimal notation.
Such a buffer can be obtained using write_hex_to(buffer)
pub fn sha1(&self) -> &[u8; 20]
[src]
Returns ourselves as slice of 20 bytes.
Panics if this instance is not a sha1 hash.
pub fn to_sha1_hex(&self) -> [u8; 40]
[src]
Return ourselves as array of 40 hexadecimal bytes.
Panics if this instance is not a sha1 hash.
pub fn to_sha1_hex_string(&self) -> String
[src]
Return ourselves as hexadecimal string with a length of 40 bytes.
Panics if this instance is not a sha1 hash.
pub fn new_sha1(id: [u8; 20]) -> Self
[src]
Instantiate an Digest from 20 bytes of a Sha1 digest.
pub fn from_20_bytes(b: &[u8]) -> Digest
[src]
Instantiate an Digest from a slice 20 borrowed bytes of a Sha1 digest.
Panics of the slice doesn't have a length of 20.
pub fn from_borrowed_sha1(b: &[u8; 20]) -> Digest
[src]
Instantiate an Digest from a borrowed array of 20 bytes of a Sha1 digest.
pub fn null_sha1() -> Digest
[src]
Returns an Digest representing a Sha1 with whose memory is zeroed.
Methods from Deref<Target = [u8; 20]>
pub fn as_slice(&self) -> &[T]
[src]
array_methods
)Returns a slice containing the entire array. Equivalent to &s[..]
.
pub fn each_ref(&self) -> [&T; N]
[src]
array_methods
)Borrows each element and returns an array of references with the same
size as self
.
Example
#![feature(array_methods)] let floats = [3.1, 2.7, -1.0]; let float_refs: [&f64; 3] = floats.each_ref(); assert_eq!(float_refs, [&3.1, &2.7, &-1.0]);
This method is particularly useful if combined with other methods, like
map
. This way, you can can avoid moving the original
array if its elements are not Copy
.
#![feature(array_methods, array_map)] let strings = ["Ferris".to_string(), "♥".to_string(), "Rust".to_string()]; let is_ascii = strings.each_ref().map(|s| s.is_ascii()); assert_eq!(is_ascii, [true, false, true]); // We can still access the original array: it has not been moved. assert_eq!(strings.len(), 3);
