Struct ParamRange 

pub struct ParamRange { /* private fields */ }

A range of parameters in the ParamArena.

This is a lightweight handle (8 bytes) that replaces four Vecs (96+ bytes) in FunctionInfo and MethodInfo.

Implementations

impl ParamRange

pub const EMPTY: ParamRange

Creates an empty parameter range.

pub fn len(&self) -> usize

Returns the number of parameters in this range.

pub fn is_empty(&self) -> bool

Returns true if this range contains no parameters.

Trait Implementations

impl Clone for ParamRange

fn clone(&self) -> ParamRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParamRange

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

Formats the value using the given formatter.

impl Default for ParamRange

fn default() -> ParamRange

Returns the “default value” for a type.

impl Hash for ParamRange

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 PartialEq for ParamRange

fn eq(&self, other: &ParamRange) -> 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.
