Struct Input

pub struct Input<'a> { /* private fields */ }

A wrapper around &'a [u8] that helps in writing panic-free code.

No methods of Input will ever panic.

Intentionally avoids implementing PartialEq and Eq to avoid implicit non-constant-time comparisons.

Implementations

impl<'a> Input<'a>

pub const fn from(bytes: &'a [u8]) -> Self

Construct a new Input for the given input bytes.

pub fn is_empty(&self) -> bool

Returns true if the input is empty and false otherwise.

pub fn len(&self) -> usize

Returns the length of the Input.

pub fn read_all<F, R, E>(&self, incomplete_read: E, read: F) -> Result<R, E>

where F: FnOnce(&mut Reader<'a>) -> Result<R, E>,

Calls read with the given input as a Reader, ensuring that read consumed the entire input. If read does not consume the entire input, incomplete_read is returned.

pub fn as_slice_less_safe(&self) -> &'a [u8]

Access the input as a slice so it can be processed by functions that are not written using the Input/Reader framework.

Trait Implementations

impl<'a> Clone for Input<'a>

fn clone(&self) -> Input<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Input<'_>

The value is intentionally omitted from the output to avoid leaking secrets.

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

Formats the value using the given formatter.

impl<'a> From<&'a [u8]> for Input<'a>

fn from(value: &'a [u8]) -> Self

Converts to this type from the input type.

impl<'a> Copy for Input<'a>

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
