struct RustcMirAttrs {
    basename_and_suffix: Option<PathBuf>,
    formatter: Option<Symbol>,
}

Fields

basename_and_suffix: Option<PathBuf>

formatter: Option<Symbol>

Implementations

impl RustcMirAttrs

fn parse(tcx: TyCtxt<'_>, def_id: DefId) -> Result<Self, ()>

fn set_field<T>( field: &mut Option<T>, tcx: TyCtxt<'_>, attr: &NestedMetaItem, mapper: impl FnOnce(Symbol) -> Result<T, ()> ) -> Result<(), ()>

fn output_path(&self, analysis_name: &str) -> Option<PathBuf>

Returns the path where dataflow results should be written, or None borrowck_graphviz_postflow was not specified.

This performs the following transformation to the argument of borrowck_graphviz_postflow:

“path/suffix.dot” -> “path/analysis_name_suffix.dot”

Trait Implementations

impl Default for RustcMirAttrs

fn default() -> RustcMirAttrs

Returns the “default value” for a type.

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.
