Struct rhai::Namespace

#[non_exhaustive]
pub struct Namespace {
    pub path: StaticVec<Ident>,
    pub index: Option<NonZeroUsize>,
}

(internals) A chain of module names to namespace-qualify a variable or function call. Exported under the internals feature only.

Not available under no_module.

A u64 offset to the current stack of imported modules in the global runtime state is cached for quick search purposes.

A StaticVec is used because the vast majority of namespace-qualified access contains only one level, and it is wasteful to always allocate a Vec with one element.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

path: StaticVec<Ident>

Path segments.

index: Option<NonZeroUsize>

Cached index into the current stack of imported modules, if any.

Implementations

impl Namespace

pub const NONE: Self = _

Constant for no namespace.

pub fn is_empty(&self) -> bool

Is this Namespace empty?

pub fn position(&self) -> Position

Get the position of this Namespace.

Panics

Panics if the path is empty.

pub fn root(&self) -> &str

Get the first path segment of this Namespace.

Panics

Panics if the path is empty.

Trait Implementations

impl Clone for Namespace

fn clone(&self) -> Namespace

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Namespace

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

Formats the value using the given formatter.

impl Default for Namespace

fn default() -> Namespace

Returns the “default value” for a type.

impl Display for Namespace

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

Formats the value using the given formatter.

impl Hash for Namespace

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 Namespace

fn eq(&self, other: &Namespace) -> 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 Eq for Namespace

impl StructuralPartialEq for Namespace
