Struct Percent 

pub struct Percent(/* private fields */);

Percentage in 0.0..=100.0. Construction outside that range returns None so normalizers can translate to ParseError::InvalidValue.

Implementations

impl Percent

pub fn new(value: f32) -> Option<Self>

pub fn from_f64(value: f64) -> Option<Self>

Construct from an f64 (JSON’s native number width). Range check runs before narrowing, so values like 100.0000001 that would round down to 100.0 in the cast are rejected rather than silently accepted.

pub fn from_f64_clamped(value: f64) -> Option<Self>

Construct from an f64, clamping finite out-of-range values into 0.0..=100.0. Returns None only for NaN. Use this when a field’s upstream producer is known to emit values slightly past 100 (e.g. Claude Code’s context_window.used_percentage post-/compact, see claude-code#37163). Callers that want visibility into the clamp should compare the raw value against the range before invoking and emit a diagnostic — this helper is silent.

pub fn value(self) -> f32

pub fn complement(self) -> Self

100.0 - self, always in-range.

Trait Implementations

impl Clone for Percent

fn clone(&self) -> Percent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Percent

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

Formats the value using the given formatter.

impl PartialEq for Percent

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

fn partial_cmp(&self, other: &Percent) -> 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 Percent

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
