Struct untrusted::Input

source ·
pub struct Input<'a> { /* private fields */ }
Expand description

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

No methods of Input will ever panic.

Implementations§

source§

impl<'a> Input<'a>

source

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

Construct a new Input for the given input bytes.

source

pub fn is_empty(&self) -> bool

Returns true if the input is empty and false otherwise.

source

pub fn len(&self) -> usize

Returns the length of the Input.

source

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.

source

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.

source§

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

source§

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

Converts to this type from the input type.
source§

impl PartialEq<[u8]> for Input<'_>

source§

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

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
