What a name is for, so a reference can group it.

Variants

Form

Evaluation forms: conditionals, bindings, quoting.

Lisp

tatara-lisp forms whose arguments are Lisp shapes; usable from blue only where the shape is plain values.

Number

Text

List

Map

Function

Functions that take or return functions.

Predicate

Questions about a value’s kind or sign.

Error

Json

Nix

Xml

File

Process

Environment

Clock

Network

NATS and HTTP over TCP.

Crypto

Lazy

Delayed values.

Concurrency

tatara-lisp’s channels and fibers.

Actor

blue’s own processes: spawn, mailboxes, links, supervision.

Output

Printing to the terminal.

Dispatch

The master verbs, dispatched on the subject’s space.

Implementations

impl Topic

pub const ALL: &'static [Topic]

Every topic, in the order a reference presents them.

pub fn title(self) -> &'static str

The heading a reference gives the topic.

pub fn effect(self) -> Option<Effect>

What calling a name of this topic may do besides compute its answer from its arguments; None when that is all it does. Exhaustive, so a new topic decides here. The call memo (blue-lang-mondou’s reach) answers a call from its cache only when nothing the definition reaches has an effect.

impl Topic

pub const fn kinded(self) -> bool

Trait Implementations

impl Clone for Topic

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Topic

impl Debug for Topic

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

Formats the value using the given formatter.

impl Eq for Topic

impl Ord for Topic

fn cmp(&self, other: &Self) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Topic

fn eq(&self, other: &Self) -> bool

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Topic

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