Implementations

impl PrefValue

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

Projects this PrefValue as &str, if it is a String. Returns None otherwise.

pub fn as_i32(&self) -> Option<i32>

Projects this PrefValue as i32, if it is an Int. Returns None otherwise.

pub fn as_bool(&self) -> Option<bool>

Projects this PrefValue as bool, if it is a Bool. Returns None otherwise.

pub fn into_string(self) -> Option<String>

Consumes this PrefValue and attempts to take a String out of it.

Trait Implementations

impl Clone for PrefValue

fn clone(&self) -> PrefValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrefValue

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

Formats the value using the given formatter.

impl From<String> for PrefValue

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<bool> for PrefValue

fn from(b: bool) -> Self

Converts to this type from the input type.

impl From<i32> for PrefValue

fn from(i: i32) -> Self

Converts to this type from the input type.

impl Hash for PrefValue

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 PrefValue

fn cmp(&self, other: &PrefValue) -> 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 PrefValue

fn eq(&self, other: &PrefValue) -> 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 PrefValue

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