Struct rustc_resolve::Segment

pub(crate) struct Segment {
    pub(crate) ident: Ident,
    pub(crate) id: Option<NodeId>,
    pub(crate) has_generic_args: bool,
    pub(crate) has_lifetime_args: bool,
    pub(crate) args_span: Span,
}

A minimal representation of a path segment. We use this in resolve because we synthesize ‘path segments’ which don’t have the rest of an AST or HIR PathSegment.

Fields

ident: Ident

id: Option<NodeId>

has_generic_args: bool

Signals whether this PathSegment has generic arguments. Used to avoid providing nonsensical suggestions.

has_lifetime_args: bool

Signals whether this PathSegment has lifetime arguments.

args_span: Span

Implementations

impl Segment

pub(crate) fn from_path(path: &Path) -> Vec<Segment>

pub(crate) fn from_ident(ident: Ident) -> Segment

pub(crate) fn from_ident_and_id(ident: Ident, id: NodeId) -> Segment

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
