Struct ssri::IntegrityOpts

pub struct IntegrityOpts { /* private fields */ }

Builds a new Integrity, allowing multiple algorithms and incremental input.

Examples

use ssri::{Algorithm, IntegrityOpts};
let contents = b"hello world";
let sri = IntegrityOpts::new()
    .algorithm(Algorithm::Sha512)
    .algorithm(Algorithm::Sha1)
    .chain(&contents)
    .result();

Implementations

impl IntegrityOpts

pub fn new() -> IntegrityOpts

Creates a new hashing IntegrityOpts.

pub fn algorithm(self, algo: Algorithm) -> Self

Generate a hash for this algorithm. Can be called multiple times to generate an Integrity string with multiple entries.

pub fn input<B: AsRef<[u8]>>(&mut self, input: B)

Add some data to this IntegrityOpts. All internal hashers will be updated for all configured Algorithms.

pub fn chain<B: AsRef<[u8]>>(self, input: B) -> Self

Same as IntegrityOpts::input, but allows chaining.

pub fn reset(&mut self)

Resets internal state for this IntegrityOpts.

pub fn result(self) -> Integrity

Generate a new Integrity from the inputted data and configured algorithms.

Trait Implementations

impl Clone for IntegrityOpts

fn clone(&self) -> IntegrityOpts

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for IntegrityOpts

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for IntegrityOpts

fn default() -> IntegrityOpts

Returns the “default value” for a type.

impl Reset for IntegrityOpts

fn reset(&mut self)

Reset state to its initial value.

impl Update for IntegrityOpts

fn update(&mut self, data: &[u8])

Update state using the provided data.

fn chain(self, input: impl AsRef<[u8]>) -> Self

Digest input data in a chained manner.

impl Write for IntegrityOpts

fn write(&mut self, buf: &[u8]) -> Result<usize>

Write a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, fmt: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Selfwhere Self: Sized,

Creates a “by reference” adapter for this instance of Write.
