Struct ResultSets 

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

Hands a format plugin its result sets one at a time, in order.

Implementations

impl ResultSets<'_>

pub fn warn(&mut self, message: impl Into<String>)

Tell the person something about the output, shown as a warning by core.

pub fn request_fonts( &mut self, font: FontRequest, ) -> Result<Result<Vec<String>, FontError>>

Ask core for an immutable registry font after consuming all result sets. Only call when WriteRequest::font_requests is true. The outer error is a protocol failure; the inner one is core’s reason it couldn’t supply the font.

pub fn next_set(&mut self) -> Result<Option<ResultSet<'_>>>

The next result set, or None after the last. Each must be read (or is drained) before the next is requested.
