Struct TailStr 

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

Borrowed final UTF-8 tail.

The raw bytes consume the remaining dynamic-tail payload. UTF-8 is checked only when the caller asks for &str, so binary-safe inspection and strict text validation are both available without copying.

Implementations

impl<'a> TailStr<'a>

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

Borrow bytes as a final UTF-8 tail.

pub const fn from_str(value: &'a str) -> Self

Borrow a string as a final UTF-8 tail.

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

Return the raw UTF-8 bytes without validating again.

pub fn as_str(&self) -> Result<&'a str, ProgramError>

Validate and return the tail as UTF-8.

pub const fn len(&self) -> usize

Number of raw UTF-8 bytes.

pub const fn is_empty(&self) -> bool

Whether the raw tail is empty.
