Elaborate the term of a forward rule in the current goal.
Equations
Instances For
Create a one-element match. subst
is the substitution that results from
matching a hypothesis against slot 0, or from a pattern substitution.
isPatSubst
is true
if the substitution resulted from a rule pattern.
forwardDeps
are the forward dependencies of slot 0. conclusionDeps
are the
conclusion dependencies of the rule to which this match belongs.
Equations
Instances For
Add a hyp or pattern substitution to the match. subst
is the substitution
that results from matching a hypothesis against slot m.level + 1
, or from the
pattern. isPatSubst
is true
if the substitution resulted from a pattern
substitution. forwardDeps
are the forward dependencies of slot
m.level + 1
.

Returns true
if the match contains the given pattern substitution.
Equations
Instances For
Given a complete match m
for r
, get arguments to r
contained in the
match's slots and substitution. For non-immediate arguments, we return none
.
The returned levels are suitable assignments for the level mvars of r
.

Apply a forward rule match to a goal. This adds the hypothesis corresponding
to the match to the local context. Returns the new goal, the added hypothesis
and the hypotheses that were removed (if any). Hypotheses may be removed if the
match is for a destruct
rule. If the skip
function, when applied to the
normalised type of the new hypothesis, returns true, then the hypothesis is not
added to the local context.

Convert forward rule matches to norm rules. Fails if any of the matches is not a norm rule match.

Convert forward rule matches to safe rules. Fails if any of the matches is not a safe rule match.

Convert forward rule matches to unsafe rules. Fails if any of the matches is not an unsafe rule match.
