Struct SourceDecl 

pub struct SourceDecl {
    pub name: String,
    pub name_span: ExprSpan,
    pub type_name: Option<TypeExpr>,
    pub initializer: Option<Expr>,
    pub filter: Option<CellFilter>,
    pub require: Option<RequireBlock>,
    pub leading_comment: Option<Comment>,
    pub doc_comment: Option<String>,
    pub trailing_line_comment: Option<Comment>,
    pub blank_line_before: bool,
    pub span: ExprSpan,
}

source_decl = "source" identifier cell_type_init [ cell_filter ] [ "require" "{" { requirement } "}" ] ";".

Same shape as CellDecl: a source cell’s initializer is a one-time literal exactly like a plain cell’s, and it supports the same filter clause and require block.

Fields

name: String

The source cell’s declared name.

name_span: ExprSpan

The name token’s span.

type_name: Option<TypeExpr>

The : type_expr annotation, if present.

initializer: Option<Expr>

The = expression initializer, if present. Unresolved and unevaluated here — see crate::parser::AdamParser for the compile-to-Sheet phase, which parses this with no cell scope pushed and evaluates it eagerly, once, at parse time.

filter: Option<CellFilter>

The filter clause, if present.

require: Option<RequireBlock>

The require { ... } validation block, if present.

leading_comment: Option<Comment>

A leading ////* */ comment immediately preceding this declaration, if recovered by crate::trivia::attach_trivia.

doc_comment: Option<String>

A leading /// doc comment immediately preceding this declaration, if recovered by crate::AdamAstParser.

trailing_line_comment: Option<Comment>

A ////* */ comment on the same source line as this declaration’s own last token, if recovered by crate::trivia::attach_trivia. See https://github.com/stlab/cel-rs/issues/59.

blank_line_before: bool

Whether a blank line preceded this declaration, if recovered by crate::trivia::attach_trivia.

span: ExprSpan

The span of the whole source ...; declaration.
