source§

impl<'tcx, 'body> ParseCtxt<'tcx, 'body>

source

fn preparse(&self, expr_id: ExprId) -> ExprId

Expressions should only ever be matched on after preparsing them. This removes extra scopes we don’t care about.

source

fn statement_as_expr(&self, stmt_id: StmtId) -> Result<ExprId, ParseError>

source

pub(crate) fn parse_args( &mut self, params: &IndexSlice<ParamId, Param<'tcx>>, ) -> Result<(), ParseError>

source

pub(crate) fn parse_body(&mut self, expr_id: ExprId) -> Result<(), ParseError>

Bodies are of the form:

{
    let bb1: BasicBlock;
    let bb2: BasicBlock;
    {
        let RET: _;
        let local1;
        let local2;

        {
            { // entry block
                statement1;
                terminator1
            };

            bb1 = {
                statement2;
                terminator2
            };

            bb2 = {
                statement3;
                terminator3
            }

            RET
        }
    }
}

This allows us to easily parse the basic blocks declarations, local declarations, and basic block definitions in order.
