Struct ckb_types::packed::BytesReader

pub struct BytesReader<'r>(_);

Implementations

impl<'r> BytesReader<'r>

pub const ITEM_SIZE: usize

pub fn total_size(&self) -> usize

pub fn item_count(&self) -> usize

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn get(&self, idx: usize) -> Option<ByteReader<'r>>

pub fn get_unchecked(&self, idx: usize) -> ByteReader<'r>

pub fn raw_data(&self) -> &'r [u8]

impl<'r> BytesReader<'r>

pub fn as_utf8(&self) -> Result<&str, Utf8Error>

Converts self to a string slice.

pub unsafe fn as_utf8_unchecked(&self) -> &str

Converts self to a string slice without checking that the string contains valid UTF-8.

Safety

This function is unsafe because it does not check that the bytes passed to it are valid UTF-8. If this constraint is violated, undefined behavior results, as the rest of Rust assumes that &strs are valid UTF-8.

pub fn is_utf8(&self) -> bool

Checks whether self is contains valid UTF-8 binary data.

impl<'r> BytesReader<'r>

pub fn calc_raw_data_hash(&self) -> Byte32

Calculates the hash for raw data in Bytes.

Returns the empty hash if no data, otherwise, calculates the hash of the data and returns it.
