Struct untrusted::Input

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

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

No methods of Input will ever panic.

Methods

impl<'a> Input<'a>

pub fn from(bytes: &'a [u8]) -> Input<'a>

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 iter(&self) -> <&[u8] as IntoIterator>::IntoIter

Returns an iterator over the input.

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 read_all_mut<F, R, E>(&self, incomplete_read: E, read: F) -> Result<R, E> where
    F: FnMut(&mut Reader<'a>) -> Result<R, E>, 

Like read_all, except taking an FnMut.

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, 'b> PartialEq<Input<'b>> for Input<'a>

fn eq(&self, other: &Input<'b>) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl<'a, 'b> PartialEq<&'b [u8]> for Input<'a>

fn eq(&self, other: &&[u8]) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl<'a> Eq for Input<'a>

impl<'a> Debug for Input<'a>

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

Formats the value using the given formatter.

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

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.
