Struct ParamIdx 

#[repr(transparent)]
pub struct ParamIdx(pub u32);

Index into a per-parameter optimizer-state buffer.

The optimizer enumerates trainable parameters in registration order. ParamIdx(0) always refers to the first registered parameter, ParamIdx(1) to the second, etc. This is not a graph-node index (those are cjc_ad::NodeIdx); the two integer spaces are unrelated even though both number from zero.

Tuple Fields

0: u32

Implementations

impl ParamIdx

pub fn from_usize(i: usize) -> Self

pub fn index(self) -> usize

Trait Implementations

impl Clone for ParamIdx

fn clone(&self) -> ParamIdx

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParamIdx

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

Formats the value using the given formatter.

impl Display for ParamIdx

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

Formats the value using the given formatter.

impl From<ParamIdx> for usize

fn from(idx: ParamIdx) -> Self

Converts to this type from the input type.

impl Hash for ParamIdx

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 ParamIdx

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

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

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