        len: u8,
    },

    Boxed {
        buf: Box<[E]>,
        len: usize,
    },
    Empty,
}

A fixed-capacity or heap-allocated buffer storing elements of type E.

Small buffers (up to 256 elements) are stored inline; larger ones use heap allocation.

Implementations

impl<E> Str<E>

pub unsafe fn as_slice(&self) -> &[E]

Returns a slice of the stored elements.

pub fn as_ptr(&self) -> *const E

Returns a raw pointer to the buffer.

pub unsafe fn as_mut_ptr(&mut self) -> *mut E

Returns an unsafe mutable raw pointer to the buffer.

pub fn len(&self) -> usize

Returns the number of elements in the buffer.

Trait Implementations

impl From<Str<u8>> for String

fn from(value: UTF8) -> Self

Converts to this type from the input type.

impl<E: Hash> Hash for Str<E>

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<E> Ord for Str<E>

fn cmp(&self, other: &Self) -> 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<E> PartialEq for Str<E>

fn eq(&self, other: &Self) -> 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<E> PartialOrd for Str<E>

fn partial_cmp(&self, other: &Self) -> 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.
