Enum ImportSpec 

#[non_exhaustive]
pub enum ImportSpec {
    Query {
        source: Cow<'static, str>,
        kind_map: fn(&str) -> ImportKind,
    },
    Custom(fn(&str, &Tree) -> Vec<RawImport>),
}

Import-extraction strategy for a language. Stage B supplies the extractors; the shape is fixed here so registering one later is not a public-API break.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Query

Extract imports with a tree-sitter query whose capture names map to import kinds.

Fields

source: Cow<'static, str>

Tree-sitter query source.

kind_map: fn(&str) -> ImportKind

Maps a query capture name to the import kind it represents.

Custom(fn(&str, &Tree) -> Vec<RawImport>)

Extract imports with a language-specific syntax-tree walker, for languages a flat query cannot express (Rust use-trees).
