[−][src]Enum wast::AssertExpression

    F32(NanPattern<Float32>),
    F64(NanPattern<Float64>),

}

An expression that is valid inside an assert_return directive.

As of https://github.com/WebAssembly/spec/pull/1104, spec tests may include assert_return directives that allow NaN patterns ("nan:canonical", "nan:arithmetic"). Parsing an AssertExpression means that:

  • only constant values (e.g. i32.const 4) are used in the assert_return directive
  • the NaN patterns are allowed (they are not allowed in regular Expressions).
