Struct rlp::Rlp

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

Data-oriented view onto rlp-slice.

This is an immutable structure. No operations change it.

Should be used in places where, error handling is required, eg. on input

Implementations

impl<'a> Rlp<'a>

pub const fn new(bytes: &'a [u8]) -> Rlp<'a>

pub fn as_raw<'view>(&'view self) -> &'a [u8]

where 'a: 'view,

pub fn prototype(&self) -> Result<Prototype, DecoderError>

pub fn payload_info(&self) -> Result<PayloadInfo, DecoderError>

pub fn data<'view>(&'view self) -> Result<&'a [u8], DecoderError>

where 'a: 'view,

pub fn item_count(&self) -> Result<usize, DecoderError>

pub fn size(&self) -> usize

pub fn at<'view>(&'view self, index: usize) -> Result<Rlp<'a>, DecoderError>

where 'a: 'view,

Returns an Rlp item in a list at the given index.

Returns an error if this Rlp is not a list or if the index is out of range.

pub fn at_with_offset<'view>( &'view self, index: usize, ) -> Result<(Rlp<'a>, usize), DecoderError>

where 'a: 'view,

Returns an Rlp item in a list at the given index along with the byte offset into the raw data slice.

Returns an error if this Rlp is not a list or if the index is out of range.

Trait Implementations

impl<'a> Clone for Rlp<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Rlp<'a>

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

Formats the value using the given formatter.

impl<'a> Display for Rlp<'a>

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

Formats the value using the given formatter.

impl<'a, 'view> IntoIterator for &'view Rlp<'a>

where 'a: 'view,

type Item = Rlp<'a>

The type of the elements being iterated over.

type IntoIter = RlpIterator<'a, 'view>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
