Struct capnp::text::Reader

pub struct Reader<'a>(pub &'a [u8]);

Wrapper around utf-8 encoded text. This is defined as a tuple struct to allow pattern matching on it via byte literals (for example text::Reader(b"hello")).

Tuple Fields

0: &'a [u8]

Implementations

impl<'a> Reader<'a>

pub fn len(&self) -> usize

The string’s length, in bytes.

pub fn is_empty(&self) -> bool

pub fn as_bytes(self) -> &'a [u8]

pub fn to_str(self) -> Result<&'a str, Utf8Error>

Converts to a str, returning a error if the data contains invalid utf-8.

pub fn to_string(self) -> Result<String, Utf8Error>

Converts to a String, returning a error if the data contains invalid utf-8.
