CompileOption is a function used to change DefaultCompileOptions.
type CompileOption func(o *CompileOptions)
func WithCompileMaxInlineDepth(depth int) CompileOption
WithCompileMaxInlineDepth sets the max depth of inline compile in decoder and encoder.
For large nested struct, try to set smaller depth to reduce compiling time.
func WithCompileRecursiveDepth(loop int) CompileOption
WithCompileRecursiveDepth sets the loop times of recursive pretouch in both decoder and encoder, for both concrete type and its pointer type.
For deep nested struct (depth exceeds MaxInlineDepth), try to set more loops to completely compile, thus reduce JIT unstability in the first hit.
CompileOptions includes all options for encoder or decoder compiler.
type CompileOptions struct {
// the maximum depth for compilation inline
MaxInlineDepth int
// the loop times for recursively pretouch
RecursiveDepth int
}
func DefaultCompileOptions() CompileOptions
DefaultCompileOptions set default compile options.
