Struct PrimitiveRegistry 

pub struct PrimitiveRegistry { /* private fields */ }

Maps primitive control sequence names to their dispatch opcodes and semantic kinds.

Implementations

impl PrimitiveRegistry

pub fn from_specs( specs: &[PrimitiveSpec], ) -> Result<Self, PrimitiveRegistryError>

Builds a registry from a slice of specs, returning an error on the first duplicate name.

pub fn insert( &mut self, spec: &PrimitiveSpec, ) -> Result<(), PrimitiveRegistryError>

Inserts a single primitive spec, returning an error if the name is already registered.

pub fn get(&self, name: &str) -> Option<&PrimitiveEntry>

Look up a primitive by control sequence name without leading backslash.

pub fn len(&self) -> usize

Returns the number of registered primitives.

pub fn is_empty(&self) -> bool

Returns true when no primitives have been registered.

Trait Implementations

impl Clone for PrimitiveRegistry

fn clone(&self) -> PrimitiveRegistry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrimitiveRegistry

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

Formats the value using the given formatter.

impl Default for PrimitiveRegistry

fn default() -> PrimitiveRegistry

Returns the “default value” for a type.

impl Eq for PrimitiveRegistry

impl PartialEq for PrimitiveRegistry

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