Struct HopperAuthoringString 

pub struct HopperAuthoringString<'a, const N: usize> { /* private fields */ }

Lifetime-shaped bounded UTF-8 authoring value.

Hopper account macros accept String<'a, N> as the canonical pretty dynamic-field syntax and lower it into the compact tail model. This wrapper makes the same spelling available to type checkers without changing the owned runtime representation, which remains HopperString<N>.

Implementations

impl<'a, const N: usize> HopperAuthoringString<'a, N>

pub const fn as_hopper(&self) -> &HopperString<N>

pub fn into_hopper(self) -> HopperString<N>

pub fn set_str(&mut self, value: &str) -> Result<()>

pub fn as_str(&self) -> Result<&str>

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

Trait Implementations

impl<'a, const N: usize> Clone for HopperAuthoringString<'a, N>

fn clone(&self) -> HopperAuthoringString<'a, N>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, const N: usize> Default for HopperAuthoringString<'a, N>

fn default() -> Self

Returns the “default value” for a type.

impl<'a, const N: usize> PartialEq for HopperAuthoringString<'a, N>

fn eq(&self, other: &HopperAuthoringString<'a, N>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a, const N: usize> TailCodec for HopperAuthoringString<'a, N>

const MAX_ENCODED_LEN: usize = HopperString<N>::MAX_ENCODED_LEN

Upper bound on the encoded size. Used by generated helpers to verify the account has enough room before invoking encode. Implementors should pick the smallest valid bound. Hopper uses this to pre-size reallocs.

fn encode(&self, out: &mut [u8]) -> Result<usize>

Serialize self into out. Returns the number of bytes written (always <= MAX_ENCODED_LEN). Fails with AccountDataTooSmall when out.len() < encoded_len.

fn decode(input: &[u8]) -> Result<(Self, usize)>

Deserialize from input. Returns (value, bytes_consumed). Fails with InvalidAccountData on malformed encoding.
