Struct SliceReader 

pub struct SliceReader<'de> { /* private fields */ }

An efficient Reader wrapper around a slice.

Implementations

impl<'de> SliceReader<'de>

pub fn new(slice: &'de [u8]) -> SliceReader<'de>

Construct a new instance around the specified slice.

Trait Implementations

impl<'de> Reader<'de> for SliceReader<'de>

type Error = SliceUnderflow

Error type raised by the current reader.

type Mut<'this> = &'this mut SliceReader<'de> where SliceReader<'de>: 'this

Type borrowed from self.

fn borrow_mut(&mut self) -> <SliceReader<'de> as Reader<'de>>::Mut<'_>

Borrow the current reader.

fn skip<C>(&mut self, cx: &mut C, n: usize) -> Result<(), <C as Context>::Error>

where C: Context<Input = <SliceReader<'de> as Reader<'de>>::Error>,

Skip over the given number of bytes.

fn read_bytes<C, V>( &mut self, cx: &mut C, n: usize, visitor: V, ) -> Result<<V as ValueVisitor<'de, C, [u8]>>::Ok, <C as Context>::Error>

where C: Context, <C as Context>::Input: From<<SliceReader<'de> as Reader<'de>>::Error>, V: ValueVisitor<'de, C, [u8]>,

Read a slice out of the current reader.

fn peek<C>(&mut self, _: &mut C) -> Result<Option<u8>, <C as Context>::Error>

where C: Context<Input = <SliceReader<'de> as Reader<'de>>::Error>,

Peek the next value.

fn read<C>( &mut self, cx: &mut C, buf: &mut [u8], ) -> Result<(), <C as Context>::Error>

where C: Context<Input = <SliceReader<'de> as Reader<'de>>::Error>,

Read a slice into the given buffer.

fn read_byte<C>(&mut self, cx: &mut C) -> Result<u8, <C as Context>::Error>

where C: Context<Input = Self::Error>,

Read a single byte.

fn read_array<C, const N: usize>( &mut self, cx: &mut C, ) -> Result<[u8; N], <C as Context>::Error>

where C: Context<Input = Self::Error>,

Read an array out of the current reader.

fn limit(self, limit: usize) -> Limit<Self>

where Self: Sized,

Keep an accurate record of the position within the reader.
