Expand description

Session builder.

Implementations§

Source§

impl SessionBuilder

Source

pub fn dcx(self, dcx: DiagCtxt) -> Self

Sets the diagnostic context. This is required.

See also the with_*_emitter* methods.

Source

pub fn source_map(self, source_map: Arc<SourceMap>) -> Self

Sets the source map.

Source

pub fn opts(self, opts: Opts) -> Self

Sets the compiler options.

Source

pub fn with_test_emitter(self) -> Self

Sets the diagnostic context to a test emitter.

Source

pub fn with_stderr_emitter(self) -> Self

Sets the diagnostic context to a stderr emitter.

Source

pub fn with_stderr_emitter_and_color(self, color_choice: ColorChoice) -> Self

Sets the diagnostic context to a stderr emitter and a color choice.

Source

pub fn with_buffer_emitter(self, color_choice: ColorChoice) -> Self

Sets the diagnostic context to a human emitter that emits diagnostics to a local buffer.

Source

pub fn with_silent_emitter(self, fatal_note: Option<String>) -> Self

Sets the diagnostic context to a silent emitter.

Source

pub fn single_threaded(self) -> Self

Sets the number of threads to use for parallelism to 1.

Source

pub fn threads(self, threads: usize) -> Self

Sets the number of threads to use for parallelism. Zero specifies the number of logical cores.

Source

pub fn build(self) -> Session

Consumes the builder to create a new session.

The diagnostics context must be set before calling this method, either by calling dcx or by using one of the provided helper methods, like with_stderr_emitter.

§Panics

Panics if:

  • the diagnostics context is not set
  • the source map in the diagnostics context does not match the one set in the builder
