Struct BorrowedBytes 

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

Input wrapping a borrowed [[u8]] buffer.

Implementations

impl<'a> BorrowedBytes<'a>

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

Create a new instance of BorrowedBytes wrapping the given buffer.

The input will be automatically padded internally, incurring at most two times MAX_BLOCK_SIZE of memory overhead.

Trait Implementations

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

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

Converts to this type from the input type.

impl<'a> From<&'a str> for BorrowedBytes<'a>

fn from(value: &'a str) -> Self

Converts to this type from the input type.

impl Input for BorrowedBytes<'_>

type BlockIterator<'b, 'r, R, const N: usize> = BorrowedBytesBlockIterator<'r, TwoSidesPaddedInput<'b>, R, N> where Self: 'b, R: InputRecorder<&'b [u8]> + 'r

Type of the iterator used by iter_blocks, parameterized by the lifetime of source input and the size of the block.

type Error = Infallible

Type of errors that can occur when operating on this Input.

type Block<'b, const N: usize> = &'b [u8] where Self: 'b

Type of the blocks returned by the BlockIterator.

fn leading_padding_len(&self) -> usize

Return the length of the padding added at the start of the input.

fn trailing_padding_len(&self) -> usize

Return the length of the padding added at the end of the input.

fn len_hint(&self) -> Option<usize>

Return the length of the entire input, if known.

fn iter_blocks<'b, 'r, R, const N: usize>( &'b self, recorder: &'r R, ) -> Self::BlockIterator<'b, 'r, R, N>

where R: InputRecorder<&'b [u8]>,

Iterate over blocks of size N of the input. N has to be a power of two larger than 1.

fn seek_backward(&self, from: usize, needle: u8) -> Option<usize>

Search for an occurrence of needle in the input, starting from from and looking back. Returns the index of the first occurrence or None if the needle was not found.

fn seek_forward<const N: usize>( &self, from: usize, needles: [u8; N], ) -> Result<Option<(usize, u8)>, Infallible>

Search for an occurrence of any of the needles in the input, starting from from and looking forward. Returns the index of the first occurrence and the needle found, or None if none of the needles were not found.

fn seek_non_whitespace_forward( &self, from: usize, ) -> Result<Option<(usize, u8)>, Infallible>

Search for the first byte in the input that is not ASCII whitespace starting from from. Returns a pair: the index of first such byte, and the byte itself; or None if no non-whitespace characters were found.

fn seek_non_whitespace_backward(&self, from: usize) -> Option<(usize, u8)>

Search for the first byte in the input that is not ASCII whitespace starting from from and looking back. Returns a pair: the index of first such byte, and the byte itself; or None if no non-whitespace characters were found.

fn is_member_match( &self, from: usize, to: usize, member: &StringPattern, ) -> Result<bool, Self::Error>

Decide whether the slice of input between from (inclusive) and to (exclusive) matches the member (comparing bitwise, including double quotes delimiters).
