Struct BoundedString 

pub struct BoundedString<const N: usize>(/* private fields */);

Fixed-capacity UTF-8 string — bounded at compile time by const generic N.

Canonical wire = postcard::serialize_str (varint length + N-bounded UTF-8 bytes). N is not on the wire — decode checks against the const. Expanding N requires a SCHEMA_VERSION bump on the enclosing Component; shrinking is forbidden (existing records might exceed the new cap).

Implementations

impl<const N: usize> BoundedString<N>

pub const CAP: usize = N

Compile-time capacity.

pub fn new(s: &str) -> Result<Self, BoundedStringError>

Construct from a borrowed &str. Rejects over-length input.

pub fn as_str(&self) -> &str

Borrow as &str.

Trait Implementations

impl<const N: usize> Clone for BoundedString<N>

fn clone(&self) -> BoundedString<N>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<const N: usize> Debug for BoundedString<N>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de, const N: usize> Deserialize<'de> for BoundedString<N>

fn deserialize<D: Deserializer<'de>>(d: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl<const N: usize> Hash for BoundedString<N>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<const N: usize> Ord for BoundedString<N>

fn cmp(&self, other: &BoundedString<N>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<const N: usize> PartialEq for BoundedString<N>

fn eq(&self, other: &BoundedString<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<const N: usize> PartialOrd for BoundedString<N>

fn partial_cmp(&self, other: &BoundedString<N>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<const N: usize> Serialize for BoundedString<N>

fn serialize<S: Serializer>(&self, s: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
