Struct Str

pub struct Str<'scale> { /* private fields */ }

This represents a string, but defers proper decoding of it until it’s asked for, and avoids allocating.

Implementations

impl<'scale> Str<'scale>

pub fn len(&self) -> usize

The length of the string.

pub fn bytes_from_start(&self) -> &'scale [u8]

The bytes left in the input, starting from this string.

pub fn bytes_after(&self) -> Result<&'scale [u8], DecodeError>

The bytes remaining in the input after this string.

pub fn is_empty(&self) -> bool

Is the string zero bytes long?

pub fn as_str(&self) -> Result<&'scale str, DecodeError>

return a string, failing if the bytes could not be properly utf8-decoded.
