Struct gix_features::hash::Write

pub struct Write<T> {
    pub hash: Sha1,
    pub inner: T,
}

Available on crate features rustsha1 or fast-sha1 only.

A utility to automatically generate a hash while writing into an inner writer.

Fields

hash: Sha1

The hash implementation.

inner: T

The inner writer.

Implementations

impl<T> Write<T>

where T: Write,

pub fn new(inner: T, object_hash: Kind) -> Self

Create a new hash writer which hashes all bytes written to inner with a hash of kind.

Trait Implementations

impl<T> Write for Write<T>

where T: Write,

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 Self

where Self: Sized,

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