Struct RdOptionList 

pub struct RdOptionList<'a> { /* private fields */ }

A parsed, borrowed Rd option list and its non-fatal diagnostics.

Implementations

impl<'a> RdOptionList<'a>

pub fn parse(nodes: &'a [RdNode], path: RdPath) -> Result<Self, RdOptionError>

Parses plain string leaves as a comma-separated scalar option list.

R’s parse_Rd() represents a \\RdOpts body as a VERB leaf while \\Sexpr’s Rd_option content is a TEXT leaf. Both are plain string leaves, so both kinds are concatenated in source order without normalization.

path is the path of the option-content container supplied by the caller. A future \\Sexpr view passes base_path.with_option(); a future \\RdOpts view passes its own tagged-node path whose children are the option text. Pair positions are reported by pair_index, not by adding path segments.

pub fn path(&self) -> &RdPath

Returns the base path supplied to the parser.

pub fn pairs(&self) -> &[RdOptionPair<'a>]

Returns all parsed pairs in source order.

pub fn diagnostics(&self) -> &[RdOptionError]

Returns non-fatal diagnostics, in occurrence order.

pub fn typed(&self) -> RdSexprOptionOverrides

Resolves valid typed values, using the last valid occurrence per key.
