Struct TokenValueMap 

pub struct TokenValueMap { /* private fields */ }

A collection of named values indexed by string tokens.

TokenValueMap struct stores a mapping from string tokens to Value instances, allowing efficient lookup of named parameters or attributes by token.

Trait Implementations

impl Clone for TokenValueMap

fn clone(&self) -> TokenValueMap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TokenValueMap

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

Formats the value using the given formatter.

impl Default for TokenValueMap

fn default() -> TokenValueMap

Returns the “default value” for a type.

impl<const N: usize> From<[(Token, Value); N]> for TokenValueMap

fn from(arr: [(Token, Value); N]) -> Self

Converts to this type from the input type.

impl FromIterator<(Token, Value)> for TokenValueMap

fn from_iter<T: IntoIterator<Item = (Token, Value)>>(iter: T) -> Self

Creates a value from an iterator.

impl Hash for TokenValueMap

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 TokenValueMap

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