Implementations

impl StaticOrHeapString

pub fn as_str(&self) -> &str

Returns the string slice representation of the enum variant.

pub fn as_mut_str(&mut self) -> &mut str

Returns the mutable string slice representation of the enum variant.

pub fn is_empty(&self) -> bool

Returns true if the string is empty.

pub fn len(&self) -> usize

Returns the length of the string.

Trait Implementations

impl Clone for StaticOrHeapString

fn clone(&self) -> StaticOrHeapString

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StaticOrHeapString

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StaticOrHeapString

fn deserialize<D>(deserializer: D) -> Result<StaticOrHeapString, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&'static str> for StaticOrHeapString

fn from(s: &'static str) -> Self

Converts to this type from the input type.

impl From<String> for StaticOrHeapString

fn from(s: String) -> Self

Converts to this type from the input type.

impl Hash for StaticOrHeapString

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 Ord for StaticOrHeapString

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 PartialEq for StaticOrHeapString

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 PartialOrd for StaticOrHeapString

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.

impl Serialize for StaticOrHeapString

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

where S: Serializer,

Serializes the string, ignoring whether it is static or heap-allocated.
