Method Details

unifyTyReported

public boolean unifyTyReported(@NotNull
 @NotNull Term upper,
 @NotNull
 @NotNull Term lower,
 Expr loc)

Check if lower is a subtype of upper, and report a type error if it's not the case.

Returns:

true if well-typed.

See Also:

• inheritFallbackUnify(org.aya.core.term.Term, org.aya.tyck.Result, org.aya.concrete.Expr)

unifyTyReported

public boolean unifyTyReported(@NotNull
 @NotNull Term upper,
 @NotNull
 @NotNull Term lower,
 Expr loc,
 Function<UnifyInfo.Comparison,org.aya.util.reporter.Problem> p)

Parameters:

upper - Expected type

lower - Actual type

loc - The location of the expression

p - Callback to generate the error message

Returns:

true if unified successfully, false otherwise

inheritFallbackUnify

protected final Result inheritFallbackUnify(@NotNull
 @NotNull Term upper,
 @NotNull
 @NotNull Result result,
 Expr loc)

Check if lower is a subtype of upper, and try to insert implicit arguments to fulfill this goal (if possible).

Returns:

the term and type after insertion
