Struct ArgMatrix 

pub(crate) struct ArgMatrix<'tcx> {
    provided_indices: Vec<ProvidedIdx>,
    expected_indices: Vec<ExpectedIdx>,
    compatibility_matrix: Vec<Vec<Compatibility<'tcx>>>,
}

Fields

provided_indices: Vec<ProvidedIdx>

Maps the indices in the compatibility_matrix rows to the indices of the user provided inputs

expected_indices: Vec<ExpectedIdx>

Maps the indices in the compatibility_matrix columns to the indices of the expected args

compatibility_matrix: Vec<Vec<Compatibility<'tcx>>>

The first dimension (rows) are the remaining user provided inputs to match and the second dimension (cols) are the remaining expected args to match

Implementations

impl<'tcx> ArgMatrix<'tcx>

pub(crate) fn new<F: FnMut(ProvidedIdx, ExpectedIdx) -> Compatibility<'tcx>>( provided_count: usize, expected_input_count: usize, is_compatible: F, ) -> Self

fn eliminate_provided(&mut self, idx: usize)

Remove a given input from consideration

fn eliminate_expected(&mut self, idx: usize)

Remove a given argument from consideration

fn satisfy_input(&mut self, provided_idx: usize, expected_idx: usize)

“satisfy” an input with a given arg, removing both from consideration

fn eliminate_satisfied(&mut self) -> Vec<(ProvidedIdx, ExpectedIdx)>

fn find_issue(&self) -> Option<Issue>

pub(crate) fn find_errors( self, ) -> (Vec<Error<'tcx>>, IndexVec<ExpectedIdx, Option<ProvidedIdx>>)

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
