Struct CompilerConfigOptions 

pub struct CompilerConfigOptions { /* private fields */ }

Available on crate feature aot only.

Defines a group of configuration options for AOT compiler.

CompilerConfigOptions is used to set the AOT compiler related configuration options, which are

• Compiler Optimization Levels

  • O0 performs as many optimizations as possible.

  • O1 optimizes quickly without destroying debuggability

  • 02 optimizes for fast execution as much as possible without triggering significant incremental compile time or code size growth

  • O3 optimizes for fast execution as much as possible

  • Os optimizes for small code size as much as possible without triggering significant incremental compile time or execution time slowdowns

  • Oz optimizes for small code size as much as possible

• Compiler Output Formats

  • Native specifies the output format is native dynamic library (*.wasm.so)
  • Wasm specifies the output format is WebAssembly with AOT compiled codes in custom section (*.wasm).

• dump_ir determines if AOT compiler generates IR or not

• generic_binary determines if AOT compiler generates the generic binary or not.

• interruptible determines if AOT compiler generates interruptible binary or not.

The configuration options above are only effective to AOT compiler.

Implementations

impl CompilerConfigOptions

pub fn new() -> Self

Creates a new instance of CompilerConfigOptions.

pub fn out_format(self, format: CompilerOutputFormat) -> Self

Sets the output binary format of AOT compiler.

Argument

• format specifies the format of the output binary.

pub fn optimization_level(self, level: CompilerOptimizationLevel) -> Self

Sets the optimization level of AOT compiler.

Argument

• level specifies the optimization level of AOT compiler.

pub fn dump_ir(self, enable: bool) -> Self

Sets the dump IR option of AOT compiler.

Argument

• enable specifies if dump ir or not.

pub fn generic_binary(self, enable: bool) -> Self

Sets the generic binary option of AOT compiler.

Argument

• enable specifies if generate the generic binary or not when perform AOT compilation.

pub fn interruptible(self, enable: bool) -> Self

Enables or Disables the Interruptible option of AOT compiler.

This option determines to generate interruptible binary or not when compilation in AOT compiler.

Argument

• enable specifies if turn on the Interruptible option.
