Struct digest_headers::Digest
[−]
[src]
pub struct Digest { /* fields omitted */ }
Defines the Digest
type.
This type can be compared to another Digest
, or turned into a String
for use in request
headers.
Methods
impl Digest
[src]
pub fn new(body: &[u8], size: ShaSize) -> Self
[src]
Creates a new Digest
from a series of bytes representing a plaintext body and a
ShaSize
.
Example
let body = "Here's some text!"; let digest = Digest::new(body.as_bytes(), ShaSize::TwoFiftySix); println!("Digest: {}", digest);
pub fn from_base64_and_size(digest: String, size: ShaSize) -> Self
[src]
Creates a new Digest
from a base64-encoded digest String
and a ShaSize
.
Example
let sha_size = ShaSize::TwoFiftySix; let digest_str = "bFp1K/TT36l9YQ8frlh/cVGuWuFEy1rCUNpGwQCSEow="; let digest = Digest::from_base64_and_size(digest_str.to_owned(), sha_size); println!("Digest: {}", digest);
pub fn sha_size(&self) -> ShaSize
[src]
Get the ShaSize
of the current Digest
pub fn as_string(&self) -> String
[src]
Represents the Digest
as a String
.
This can be used to produce headers for HTTP Requests.
Example
let digest = Digest::new(b"Hello, world!", ShaSize::TwoFiftySix); println!("Digest: {}", digest.as_string());
pub fn verify(&self, body: &[u8]) -> Result<(), Error>
[src]
Verify a given message body with the digest.
Example
let body = b"Some message body"; let digest = Digest::new(body, ShaSize::TwoFiftySix); assert!(digest.verify(body).is_ok());
