Struct Occurrence 

pub struct Occurrence {
    pub def: DefRef,
    pub reference: Option<u32>,
}

What Index::at found at a position.

Examples

use resolve_lang::{DefRef, Occurrence};

let o = Occurrence { def: DefRef::from_index(0), reference: None };
assert!(o.is_definition());

Fields

def: DefRef

The definition named there.

reference: Option<u32>

The reference there (by position in Index::references_all), or None if the position is the definition’s own name.

Implementations

impl Occurrence

pub const fn is_definition(&self) -> bool

Whether the position is the definition’s own name.

Examples

use resolve_lang::{DefRef, Occurrence};

let o = Occurrence { def: DefRef::from_index(0), reference: Some(3) };
assert!(!o.is_definition());
