Struct preserves::value::repr::Record

pub struct Record<N>(pub Vec<N>);

A Record Value.

INVARIANT: The length of the contained vector MUST always be non-zero.

Tuple Fields

0: Vec<N>

Implementations

impl<N> Record<N>

pub fn label(&self) -> &N

Retrieve the record’s label.

pub fn label_mut(&mut self) -> &mut N

Retrieve a mutable reference to the record’s label.

pub fn arity(&self) -> usize

Retrieve the arity of the record, the number of fields it has.

pub fn fields(&self) -> &[N]

Retrieve a slice containing the fields of the record.

pub fn fields_mut(&mut self) -> &mut [N]

Retrieve a mutable slice containing the fields of the record.

pub fn fields_vec(&self) -> &Vec<N>

Retrieve a reference to a vector containing the record’s label and fields.

pub fn fields_vec_mut(&mut self) -> &mut Vec<N>

Retrieve a mutable reference to a vector containing the record’s label and fields.

pub fn finish(self) -> Value<N>

where N: NestedValue,

Converts self into a Value.

Trait Implementations

impl<N: Clone> Clone for Record<N>

fn clone(&self) -> Record<N>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<N: Debug> Debug for Record<N>

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

Formats the value using the given formatter.

impl<N: Hash> Hash for Record<N>

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<N: Ord> Ord for Record<N>

fn cmp(&self, other: &Record<N>) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl<N: PartialEq> PartialEq for Record<N>

fn eq(&self, other: &Record<N>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<N: PartialOrd> PartialOrd for Record<N>

fn partial_cmp(&self, other: &Record<N>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
