Struct Meta 

Source
pub struct Meta<T> {
    pub value: T,
    pub tag: Option<String>,
    pub span: Span,
    pub doc: Option<Vec<String>>,
}
Expand description

A value with source span and documentation.

This struct wraps a value along with:

  • Source location (for diagnostics, go-to-definition)
  • Doc comments (for hover info)

Fields§

§value: T

The wrapped value.

§tag: Option<String>

The tag associated to this value if any

§span: Span

The source span (offset and length).

§doc: Option<Vec<String>>

Documentation lines (each line is a separate string).
