Struct EarlySession 

pub struct EarlySession {
    pub target: Target,
    pub host: Target,
    pub opts: Options,
    pub psess: ParseSess,
}

Partial session built before the full session. More specifically, EarlySession is used to init the codegen backend, and then both pieces are used to build the full Session.

Fields

target: Target

host: Target

opts: Options

psess: ParseSess

Implementations

impl EarlySession

pub fn dcx(&self) -> DiagCtxtHandle<'_>

pub fn source_map(&self) -> &SourceMap

pub fn early_lto(&self) -> LtoCli

Note: this is simpler than Session::lto, hence the early_ prefix (to more clearly distinguish it).

pub fn print_llvm_stats(&self) -> bool

pub fn print_llvm_stats_json(&self) -> Option<&String>

pub fn relocation_model(&self) -> RelocModel

pub fn code_model(&self) -> Option<CodeModel>

pub fn tls_model(&self) -> TlsModel

pub fn panic_strategy(&self) -> PanicStrategy

Returns the panic strategy for this compile session. If the user explicitly selected one using ‘-C panic’, use that, otherwise use the panic strategy defined by the target.

pub fn apple_deployment_target(&self) -> OSVersion

Get the deployment target on Apple platforms based on the standard environment variables, or fall back to the minimum version supported by rustc.

This should be guarded behind if sess.target.is_like_darwin.

pub fn sanitizers(&self) -> SanitizerSet

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
