Struct NamePath 

pub struct NamePath { /* private fields */ }

A syntactic non-empty dot-separated name path.

NamePath preserves source-level path shape (Foo, module.Foo, module.Index.Variant) without assigning a semantic namespace to any segment. It is appropriate for unresolved reference positions that do not need per-segment spans. Use crate::syntax::ast::IdentPath when the AST must retain source spans for each segment.

Implementations

impl NamePath

pub const fn new(segments: NonEmpty<NameAtom>) -> Self

Construct a path from already-validated atoms.

pub fn local(atom: NameAtom) -> Self

Construct a one-segment path.

pub fn qualified_path( qualifier: impl IntoIterator<Item = NameAtom>, leaf: NameAtom, ) -> Self

Construct a path from qualifier atoms plus a leaf atom.

pub fn segments(&self) -> &[NameAtom]

Borrow all path segments in source order.

pub fn into_segments(self) -> NonEmpty<NameAtom>

Consume and return all path segments.

pub const fn len(&self) -> usize

Number of path segments. Always at least 1.

pub const fn is_empty(&self) -> bool

Returns false; provided for API compatibility with sequence-like code.

pub const fn is_bare(&self) -> bool

Returns whether this is a one-segment path.

pub fn leaf(&self) -> &NameAtom

Returns the leaf segment.

pub fn as_bare(&self) -> Option<&NameAtom>

Returns the only segment when this is a bare path.

pub fn split_last(&self) -> (&[NameAtom], &NameAtom)

Split the path into qualifier segments and leaf segment.

The qualifier slice is empty for one-segment paths.

pub fn qualifier_segments(&self) -> &[NameAtom]

Returns the qualifier segments before the leaf. Empty for bare paths.

pub fn qualifier_and_leaf(&self) -> Option<(&[NameAtom], &NameAtom)>

Returns qualifier segments and leaf only when this path is qualified.

pub fn display_path(&self) -> String

Human-readable path string for diagnostics and formatting boundaries.

Trait Implementations

Formats the value using the given formatter.

impl Eq for NamePath

impl FormatEquivalent for NamePath

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

Returns true if self and other are equivalent up to formatting.

impl From<&str> for NamePath

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<NameAtom> for NamePath

fn from(atom: NameAtom) -> Self

Converts to this type from the input type.

impl Hash for NamePath

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 Ord for NamePath

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

impl PartialEq for NamePath

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

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.
